STRs vs SNPs, Multiple DNA Personalities

Posted on February 10, 2014 by Roberta Estes

One of the questions I receive rather regularly is about the difference between STRs and SNPs.

Generally, what people really want to understand is the difference between the products, and a basic answer is really all they want. I explain that an STR or Short Tandem Repeat is a different kind of a mutation than a SNP or a Single Nucleotide Polymorphism. STRs are useful genealogically, to determine to whom you match within a recent timeframe, of say, the past 500 years or so, and SNPs define haplogroups which reach much further back in time. Furthermore SNPs are considered “once in a lifetime,” or maybe better stated, “once in the lifetime of mankind” type of events, known as a UEP, Unique Event Polymorphism, where STRs happen “all the time,” in every haplogroup. In fact, this is why you can check for the same STR markers in every haplogroup – those markers we all know and love.

This was a pretty good explanation for a long time but as sequencing technology has improved and new tests have become available, such as the Full Y and Big Y tests, new mutations are being very rapidly discovered which blurs the line between the timeframes that had been used to separate these types of tests. In fact, now they are overlapping in time, so SNPs are, in some cases becoming genealogically useful. This also means that these newly discovered family SNPs are relatively new, meaning they only occurred between the current generation and 1000 years ago, so we should not expect to find huge numbers of these newly developed mutations in the population. For example, if the SNP that defined haplogroup R1b1a2, M269, occurred 15,000 years ago in one man, his descendants have had 15,000 years to procreate and pass his M269 on down the line(s), something they have done very successfully since about half of Europe is either M269 or a subclade.

Each subclade has a SNP all its own. In fact, each subclade is defined by a specific SNP that forms its own branch of the human Y haplotree.

So far, so good.

But what does a SNP or an STR really look like, I mean, in the raw data? How do you know that you’re seeing one or the other?

Like Baseball – 4 Bases

The smallest units of DNA are made up of 4 base nucleotides, DNA words, that are represented by the following letters:

A = Adenine
C = Cytosine
G = Guanine
T = Thymine

These nucleotides combine in pairs to form the ladder rungs of DNA, shown right that connect the helix backbones. T typically combines with A and C usually combines with G, reaching between the backbones of the double helix to connect with their companion protein in the center.

You don’t need to remember the words or even the letters, just remember that we are looking for pattern matches of segments of DNA.

Point Mutations

Your DNA when represented on paper looks like a string of beads where there are 4 kinds of beads, each representing one of the nucleotides above. One segment of your DNA might look like this:

If this is what the standard or reference sequence for your haplotype (your personal DNA results) or your family haplogroup (ancestral clan) looks like, then a mutation would be defined as any change, addition, or deletion. A change would be if the first A above were to change to T or G or C as in the example below:

A deletion would be noticed if the leading A were simply gone.

An addition of course would be if a new bead were inserted in the sequence at that location.

All of the above changes involve only one location. These are all known as Point Mutations, because they occur at one single point.

SNPs

A point mutation may or may not be a SNP. A SNP is defined by geneticists as a point mutation that is found in more than 1% of the population. This should tell you right away that when we say “we’ve discovered a new SNP,” we’re really mis-applying that term, because until we determine that the frequency which it is found in the population is over the 1% threshold, it really isn’t a SNP, but is still considered a point mutation or binary polymorphism.

Today, when SNPS, or point mutations are discovered, they are considered “private mutations” or “family mutations.” There has been consternation for some time about how to handle these types of situations. ISOGG has set forth their criteria on their website. They currently have the most comprehensive tree, but they certainly have their work cut out for them with the incoming tsunami of new SNPS that will be discovered utilizing these next generation tests, hundreds of which are currently in process.

STRs

A STR, or Short Tandem Repeat is analogous to a genetic stutter, or the copy machine getting stuck. In the same situation as above, utilizing the same base for comparison, we see a group of inserted nucleotides that are all duplicates of each other.

In this case, we have a short tandem repeat that is 4 segments in length meaning that CT is inserted 4 times. To translate, if this is marker DYS marker 390, you have a value of 5, meaning 5 repeats of CT.

So I’ve been fat and happy with this now for years, well over a decade.

The Monkey Wrench

And then I saw this:

“The L69/L159 polymorphism is essentially a SNP/STR oxymoron.”

To the best of my knowledge, this is impossible – one type of mutation excludes the other. I googled about this topic and found nothing, nor did I find additional discussion of L69, other than this.

My first reaction to this was “that’s impossible,” followed by “Bloody Hell,” and my next reaction was to find someone who knew.

I reached out to Dr. David Mittelman, geneticist and Chief Scientific Officer at Gene by Gene, parent company of Family Tree DNA. I asked him about the SNP/STR oxymoron and he said:

“This is impossible. There is no such thing as a SNP/STR.”

Whew! I must say, I’m relieved. I thought there for a minute there I had lost my mind.

I asked him what is really going on in this sequence, and he replied that, “This would be a complex variant — when multiple things are happening at once.”

Now, that I understand. I have children, and grandchildren – I fully understand multiple things happening at once. Let’s break this example apart and take a look at what is really happening.

HUGO is a reference standard, so let’s start there as our basis for comparison.

In the L69 variant we have the following sequence.

We see two distinct things happening in this sequence. First, we have the deletion of two Gs, and secondly, we have the insertion of one additional TG. According to Dr. Mittelman, both of these events are STRs, multiple insertions or deletions, and neither are point mutations or SNPs, so neither of these should really have SNP names, they should have STR type of names.

Let’s look at the L159 variant.

In this case, we have the GG insertion and then we have a TG deletion.

In both cases, L69 and L159, the actual length of the DNA sequence remains the same as the reference, but the contents are different. Both had 2 nucleotides removed and 2 added.

The good news is, as a consumer, that you don’t really need to know this, not at this level. The even better news is that with the new discoveries forthcoming, whether they be STRs or SNPs, at the leafy end of the branch, they are often now overlapping with SNPs becoming much more genealogically useful. In the past, if you were looking at a genetics mutation timeline, you had STRs that covered current to 1000 years, then nothing, then beginning at 5,000 or 10,000 years, you have SNPs that were haplogroup defining.

That gap has been steadily shrinking, and today, there often is no gap, the chasm is gone, and we’re discovering freshly hatched recently-occurring SNPs on a daily basis.

The day is fast approaching when you’ll want the full Y sequence, not to further define your haplogroup, but to further delineate your genealogy lines. You’ll have two tools to do that, SNPs and STRs both, not just one.

The $1000 Genome? – Not Exactly

Posted on January 17, 2014 by Roberta Estes

You may have seen the headlines and the announcement this week by Illumina, manufacturer of gene sequencing equipment, that the $1000 genome is finally here. Hallelujah – jump for joy – right? Sign me up – where can I order???

Well, not so fast.

It’s a great headline – and depending on how you figure the math – it’s not entirely untrue, but it’s a real struggle to get there. Some marketing maven did some real spreadsheet magic! What is that old saying, “lies, damned lies and statistics”? Maybe that’s a little harsh, but it’s not too far off.

So, is the $1000 genome here or not? Well, kindof. It depends on how you count, and who you are. You see, it’s a math thing.

It’s kind of like a mortgage. How much did your house cost? Let’s say $100,000 – that was the price on the “for sale” sign. But by the time you get the mortgage paid off, 30 years later, the cost of that house is way more than $100,000, probably more than $250,000 and if you add in the cost of taxes, closing costs and maintenance, even more. This will only depress you, so don’t think about, especially when you sell your house for $150,000 and declare that you “made” $50,000. But I digress…

So, let’s translate this to the $1000 genome.

Dr. David Mittleman, Chief Scientific Officer for Gene by Gene, Ltd., parent company of Family Tree DNA, was at the conference this week where the Illumina announcement was made. I asked him several questions about this new technology and if it was ready for prime time yet.

His first comment shed some light on costs.

“The HiSeqX Ten system is actually a ten-pack of new HiSeq instruments, each costing 1 million dollars. So you have to spend $10 million on equipment before you can even get started.”

Ouch. I guess I won’t be buying one anytime soon!

To begin with, without the cost of the kits or processing or staff or software or installation or financing or support contracts or profit, a company would have to sell 10,000 kits at $1000 to even bring the cost of the equipment to $1000 per kit.

So, how did Illumina figure the cost of the $1000 genome? The $1000 is broken down as $800 on reagents, $135 on equipment depreciation over 4 years, and $65 on staff/overheads.

This means that to obtain that $1000 per genome price, you have to run the equipment at full capacity, 24X7, 18,000 kits per year, for 4 full years. And that still doesn’t include everything. You also need service contracts, installation, additional labor, etc. You can read more about the math and cost of ownership here.

And sure enough, when I asked David about who has purchased one so far, there are two buyers and both are institutions. This is an extremely high end product, not something for the DTC consumer marketspace.

Now this isn’t to say this announcement is a bad thing – it’s not – it’s just not exactly what the headlines suggest. It’s the $1000 genome for those with deep pockets who can purchase a $10,000,000 piece of gear and then run 18,000 samples, for 4 years, plus expenses. But yes, it does technically break down to $1000 per test as long as you hit all of those milestones and ignore the rest of the expenses. If you can afford $10 million and have the staff to run it, you probably don’t care about the cost of installation, labor and support contracts. They are just necessary incidentals – like gas for my lawn mower!

In spite of the fancy math, it’s truly amazing how far we’ve come when you consider that a single full genome sequence still cost about 3 million in 2007, and in November 2012 Gene by Gene was the first to offer full sequencing commercially and offered it to their customers for an introductory price of $5495. Of course, with no analysis tools and few testers, I can’t imagine what one would do with those results. This has changed somewhat today. The full genome with some analysis is available today to consumers for $7595, but the question of what is available that is genealogically useful to do with these results still remains, and will, until many more people test and meaningful comparisons are available.

The Illumina announcement also raises the issue of software investment to do something useful with the massive amount of data this new equipment will generate…also nontrivial, and that software does not exist yet today.

There are other issues to be addressed as well, like open access libraries. Will they exist? If so, where? Who cares for them? How are they funded? Who will have access? Will this data be made available in open access libraries, assuming they exist?

Illumina has reported that entire countries have approached them asking for their population to be sequenced, which also begs questions of privacy, security and how exactly to anonymize the samples without them becoming useless to research. This high tech watershed announcement may spur as many questions as answers, but these issues need to be resolved in the academic environment before they trickle down to the consumer marketspace.

This is not to minimize the science and technology that has propelled us to this breakthrough. It is a wonderful scientific and technological advancement because it will allow governments or large institutes to do huge population-wide studies. This is something we desperately need. Think for a minute if our Population Finder ethnicity results were based on tens of thousands of samples instead of selected hundreds.

For genetic genealogists, we are poised to benefit in the future, probably the more distant than the near future. The $1000 genome for consumers not only isn’t here, it’s not even within sniffing distance. So put your checkbooks away or better yet, buy a Big Y or a Family Finder test for a cousin, something that will benefit you in the short term.

This next step in the world of genetic discovery is exciting for research institutes, but it’s not yet ready for consumer prime time. We will be the beneficiaries, but not the direct consumers….yet…unless you want to move to one of those countries who wants their entire population sequenced. Our turn will come. Maybe the next time we see an announcement for the $1000 genome it will be calculated in normal home-owning-human terms.

2013’s Dynamic Dozen – Top Genetic Genealogy Happenings

Posted on December 28, 2013 by Roberta Estes

Last year I wrote a column at the end of the year titled “2012 Top 10 Genetic Genealogy Happenings.” It’s amazing the changes in this industry in just one year. It certainly makes me wonder what the landscape a year from now will look like.

I’ve done the same thing this year, except we have a dozen. I couldn’t whittle it down to 10, partly because there has been so much more going on and so much change – or in the case of Ancestry, who is noteworthy because they had so little positive movement.

If I were to characterize this year of genetic genealogy, I would call it The Year of the SNP, because that applies to both Y DNA and autosomal. Maybe I’d call it The Legal SNP, because it is also the year of law, court decisions, lawsuits and FDA intervention. To say it has been interesting is like calling the Eiffel Tower an oversized coat hanger.

I’ll say one thing…it has kept those of us who work and play in this industry hopping busy! I guarantee you, the words “I’m bored” have come out of the mouth of no one in this industry this past year.

I’ve put these events in what I consider to be relatively accurate order. We could debate all day about whether the SNP Tsunami or the 23andMe mess is more important or relevant – and there would be lots of arguing points and counterpoints…see…I told you lawyers were involved….but in reality, we don’t know yet, and in the end….it doesn’t matter what order they are in on the list:)

Y Chromosome SNP Tsunami Begins

The SNP tsumani began as a ripple a few years ago with the introduction at Family Tree DNA of the Walk the Y program in 2007. This was an intensively manual process of SNP discovery, but it was effective.

By the time that the Geno 2.0 chip was introduced in 2012, 12,000+ SNPs would be included on that chip, including many that were always presumed to be equivalent and not regularly tested. However, the Nat Geo chip tested them and indeed, the Y tree became massively shuffled. The resolution to this tree shuffling hasn’t yet come out in the wash. Family Tree DNA can’t really update their Y tree until a publication comes out with the new tree defined. That publication has been discussed and anticipated for some time now, but it has yet to materialize. In the mean time, the volunteers who maintain the ISOGG tree are swamped, to say the least.

Another similar test is the Chromo2 introduced this year by Britain’s DNA which scans 15,000 SNPs, many of them S SNPs not on the tree nor academically published, adding to the difficulty of figuring out where they fit on the Y tree. While there are some very happy campers with their Chromo2 results, there is also a great deal of sloppy science, reporting and interpretation of “facts” through this company. Kind of like Jekyll and Hyde. See the Sloppy Science section.

But Walk the Y, Chromo2 and Geno 2.0, are only the tip of the iceburg. The new “full Y” sequencing tests brought into the marketspace quietly in early 2013 by Full Genomes and then with a bang by Family Tree DNA with the their Big Y in November promise to revolutionize what we know about the Y chromosome by discovering thousands of previously unknown SNPs. This will in effect swamp the Y tree whose branches we thought were already pretty robust, with thousands and thousands of leaves.

In essence, the promise of the “fully” sequenced Y is that what we might term personal or family SNPs will make SNP testing as useful as STR testing and give us yet another genealogy tool with which to separate various lines of one genetic family and to ratchet down on the time that the most common recent ancestor lived.

23andMe Comes Unraveled

The story of 23andMe began as the consummate American dotcom fairy tale, but sadly, has deteriorated into a saga with all of the components of a soap opera. A wealthy wife starts what could be viewed as an upscale hobby business, followed by a messy divorce and a mystery run-in with the powerful overlording evil-step-mother FDA. One of the founders of 23andMe is/was married to the founder of Google, so funding, at least initially wasn’t an issue, giving 23andMe the opportunity to make an unprecedented contribution in the genetic, health care and genetic genealogy world.

Another way of looking at this is that 23andMe is the epitome of the American Dream business, a startup, with altruism and good health, both thrown in for good measure, well intentioned, but poorly managed. And as customers, be it for health or genealogy or both, we all bought into the altruistic “feel good” culture of helping find cures for dread diseases, like Parkinson’s, Alzheimer’s and cancer by contributing our DNA and responding to surveys.

The genetic genealogy community’s love affair with 23andMe began in 2009 when 23andMe started focusing on genealogy reporting for their tests, meaning cousin matches. We, as a community, suddenly woke up and started ordering these tests in droves. A few months later, Family Tree DNA also began offering this type of testing as well. The defining difference being that 23andMe’s primary focus has always been on health and medical information with Family Tree DNA focused on genetic genealogy. To 23andMe, the genetic genealogy community was an afterthought and genetic genealogy was just another marketing avenue to obtain more people for their health research data base. For us, that wasn’t necessarily a bad thing.

For awhile, this love affair went along swimmingly, but then, in 2012, 23andMe obtained a patent for Parkinson’s Disease. That act caused a lot of people to begin to question the corporate focus of 23andMe in the larger quagmire of the ethics of patenting genes as a whole. Judy Russell, the Legal Genealogist, discussed this here. It’s difficult to defend 23andMe’s Parkinson’s patent while flaying alive Myriad for their BRCA patent. Was 23andMe really as altruistic as they would have us believe?

Personally, this event made me very nervous, but I withheld judgment. But clearly, that was not the purpose for which I thought my DNA, and others, was being used.

But then came the Designer Baby patent in 2013. This made me decidedly uncomfortable. Yes, I know, some people said this really can’t be done, today, while others said that it’s being done anyway in some aspects…but the fact that this has been the corporate focus of 23andMe with their research, using our data, bothered me a great deal. I have absolutely no issue with using this information to assure or select for healthy offspring – but I have a personal issue with technology to enable parents who would select a “beauty child,” one with blonde hair and blue eyes and who has the correct muscles to be a star athlete, or cheerleader, or whatever their vision of their as-yet-unconceived “perfect” child would be. And clearly, based on 23andMe’s own patent submission, that is the focus of their patent.

Upon the issuance of the patent, 23andMe then said they have no intention of using it. They did not say they won’t sell it. This also makes absolutely no business sense, to focus valuable corporate resources on something you have no intention of using? So either they weren’t being truthful, they lack effective management or they’ve changed their mind, but didn’t state such.

What came next, in late 2013 certainly points towards a lack of responsible management.

23andMe had been working with the FDA for approval the health and medical aspect of their product (which they were already providing to consumers prior to the November 22^nd cease and desist order) for several years. The FDA wants assurances that what 23andMe is telling consumers is accurate. Based on the letter issued to 23andMe on November 22^nd, and subsequent commentary, it appears that both entities were jointly working towards that common goal…until earlier this year when 23andMe mysteriously “somehow forgot” about the FDA, the information they owed them, their submissions, etc. They also forgot their phone number and their e-mail addresses apparently as well, because the FDA said they had heard nothing from them in 6 months, which backdates to May of 2013.

It may be relevant that 23andMe added the executive position of President and filled it in June of 2013, and there was a lot of corporate housecleaning that went on at that time. However, regardless of who got housecleaned, the responsibility for working with the FDA falls squarely on the shoulders of the founders, owners and executives of the company. Period. No excuses. Something that critically important should be on the agenda of every executive management meeting. Why? In terms of corporate risk, this was obviously a very high risk item, perhaps the highest risk item, because the FDA can literally shut their doors and destroy them. There is little they can do to control or affect the FDA situation, except to work with the FDA, meet deadlines and engender goodwill and a spirit of cooperation. The risk of not doing that is exactly what happened.

It’s unknown at this time if 23andMe is really that corporately arrogant to think they could simply ignore the FDA, or blatantly corporately negligent or maybe simply corporately stupid, but they surely betrayed the trust and confidence of their customers by failing to meet their commitments with and to the FDA, or even communicate with them. I mean, really, what were they thinking?

There has been an outpouring of sympathy for 23andme and negative backlash towards the FDA for their letter forcing 23andMe to stop selling their offending medical product, meaning the health portion of their testing. However, in reality, the FDA was only meting out the consequences that 23andMe asked for. My teenage kids knew this would happen. If you do what you’re not supposed to….X, Y and Z will, or won’t, happen. It’s called accountability. Just ask my son about his prom….he remembers vividly. Now why my kids, or 23andMe, would push an authority figure to that point, knowing full well the consequences, utterly mystifies me. It did when my son was a teenager and it does with 23andMe as well.

Some people think that the FDA is trying to stand between consumers and their health information. I don’t think so, at least not in this case. Why I think that is because the FDA left the raw data files alone and they left the genetic genealogy aspect alone. The FDA knows full well you can download your raw data and for $5 process it at a third party site, obtaining health related genetic information. The difference is that Promethease is not interpreting any data for you, only providing information.

There is some good news in this and that is that from a genetic genealogy perspective, we seem to be safe, at least for now, from government interference with the testing that has been so productive for genetic genealogy. The FDA had the perfect opportunity to squish us like a bug (thanks to the opening provided by 23andMe,) and they didn’t.

The really frustrating aspect of this is that 23andMe was a company who, with their deep pockets in Silicon Valley and other investors, could actually afford to wage a fight with the FDA, if need be. The other companies who received the original 2010 FDA letter all went elsewhere and focused on something else. But 23andMe didn’t, they decided to fight the fight, and we all supported their decision. But they let us all down. The fight they are fighting now is not the battle we anticipated, but one brought upon themselves by their own negligence. This battle didn’t have to happen, and it may impair them financially to such a degree that if they need to fight the big fight, they won’t be able to.

Right now, 23andMe is selling their kits, but only as an ancestry product as they work through whatever process they are working through with the FDA. Unfortunately, 23andMe is currently having some difficulties where the majority of matches are disappearing from some testers records. In other cases, segments that previously matched are disappearing. One would think, with their only revenue stream for now being the genetic genealogy marketspace that they would be wearing kid gloves and being extremely careful, but apparently not. They might even consider making some of the changes and enhancements we’ve requested for so long that have fallen on deaf ears.

One thing is for sure, it will be extremely interesting to see where 23andMe is this time next year. The soap opera continues.

I hope for the sake of all of the health consumers, both current and (potentially) future, that this dotcom fairy tale has a happy ending.

Supreme Court Decision – Genes Can’t Be Patented – Followed by Lawsuits

In a landmark decision, the Supreme Court determined that genes cannot be patented. Myriad Genetics held patents on two BRCA genes that predisposed people to cancer. The cost for the tests through Myriad was about $3000. Six hours after the Supreme Court decision, Gene By Gene announced that same test for $995. Other firms followed suit, and all were subsequently sued by Myriad for patent infringement. I was shocked by this, but as one of my lawyer friends clearly pointed out, you can sue anyone for anything. Making it stick is yet another matter. Many firms settle to avoid long and very expensive legal battles. Clearly, this issue is not yet resolved, although one would think a Supreme Court decision would be pretty definitive. It potentially won’t be settled for a long time.

Gene By Gene Steps Up, Ramps Up and Produces

As 23andMe comes unraveled and Ancestry languishes in its mediocrity, Gene by Gene, the parent company of Family Tree DNA has stepped up to the plate, committed to do “whatever it takes,” ramped up the staff both through hiring and acquisitions, and is producing results. This is, indeed, a breath of fresh air for genetic genealogists, as well as a welcome relief.

Autosomal DNA Comes of Age

Autosomal DNA testing and analysis has simply exploded this past year. More and more people are testing, in part, because Ancestry.com has a captive audience in their subscription data base and more than a quarter million of those subscribers have purchased autosomal DNA tests. That’s a good thing, in general, but there are some negative aspects relative to Ancestry, which are in the Ancestry section.

Another boon to autosomal testing was the 23andMe push to obtain a million records. Of course, the operative word here is “was” but that may revive when the FDA issue is resolved. One of the down sides to the 23andMe data base, aside from the fact that it’s not genealogist friendly, is that so many people, about 90%, don’t communicate. They aren’t interested in genealogy.

A third factor is that Family Tree DNA has provided transfer ability for files from both 23andMe and Ancestry into their data base.

Fourth is the site, GedMatch, at www.gedmatch.com which provides additional matching and admixture tools and the ability to match below thresholds set by the testing companies. This is sometimes critically important, especially when comparing to known cousins who just don’t happen to match at the higher thresholds, for example. Unfortunately, not enough people know about GedMatch, or are willing to download their files. Also unfortunate is that GedMatch has struggled for the past few months to keep up with the demand placed on their site and resources.

A great deal of time this year has been spent by those of us in the education aspect of genetic genealogy, in whatever our capacity, teaching about how to utilize autosomal results. It’s not necessarily straightforward. For example, I wrote a 9 part series titled “The Autosomal Me” which detailed how to utilize chromosome mapping for finding minority ethnic admixture, which was, in my case, both Native and African American.

As the year ends, we have Family Tree DNA, 23andMe and Ancestry who offer the autosomal test which includes the relative-matching aspect. Fortunately, we also have third party tools like www.GedMatch.com and www.DNAGedcom.com, without which we would be significantly hamstrung. In the case of DNAGedcom, we would be unable to perform chromosome segment matching and triangulation with 23andMe data without Rob Warthen’s invaluable tool.

DNAGedcom – Indispensable Third Party Tool

While this tool, www.dnagedcom.com, falls into the Autosomal grouping, I have separated it out for individual mention because without this tool, the progress made this year in autosomal DNA ancestor and chromosomal mapping would have been impossible. Family Tree DNA has always provided segment matching boundaries through their chromosome browser tool, but until recently, you could only download 5 matches at a time. This is no longer the case, but for most of the year, Rob’s tool saved us massive amounts of time.

23andMe does not provide those chromosome boundaries, but utilizing Rob’s tool, you can obtain each of your matches in one download, and then you can obtain the list of who your matches match that is also on your match list by requesting each of those files separately. Multiple steps? Yes, but it’s the only way to obtain this information, and chromosome mapping without the segment data is impossible

A special hats off to Rob. Please remember that Rob’s site is free, meaning it’s donation based. So, please donate if you use the tool.

http://www.yourgeneticgenealogist.com/2013/01/brought-to-you-by-adoptiondna.html

I covered www.Gedmatch.com in the “Best of 2012” list, but they have struggled this year, beginning when Ancestry announced that raw data file downloads were available. GedMatch consists of two individuals, volunteers, who are still struggling to keep up with the required processing and the tools. They too are donation based, so don’t forget about them if you utilize their tools.

Ancestry – How Great Thou Aren’t

Ancestry is only on this list because of what they haven’t done. When they initially introduced their autosomal product, they didn’t have any search capability, they didn’t have a chromosome browser and they didn’t have raw data file download capability, all of which their competitors had upon first release. All they did have was a list of your matches, with their trees listed, with shakey leaves if you shared a common ancestor on your tree. The implication, was, and is, of course, that if you have a DNA match and a shakey leaf, that IS your link, your genetic link, to each other. Unfortunately, that is NOT the case, as CeCe Moore documented in her blog from Rootstech (starting just below the pictures) as an illustration of WHY we so desperately need a chromosome browser tool.

In a nutshell, Ancestry showed the wrong shakey leaf as the DNA connection – as proven by the fact that both of CeCe’s parents have tested at Ancestry and the shakey leaf person doesn’t match the requisite parent. And there wasn’t just one, not two, but three instances of this. What this means is, of course, that the DNA match and the shakey leaf match are entirely independent of each other. In fact, you could have several common ancestors, but the DNA at any particular location comes only from one on either Mom or Dad’s side – any maybe not even the shakey leaf person.

So what Ancestry customers are receiving is a list of people they match and possible links, but most of them have no idea that this is the case, and blissfully believe they have found their genetic connection. They have found a genealogical cousin, and it MIGHT be the genetic connection. But then again, they could have found that cousin simply by searching for the same ancestor in Ancestry’s data base. No DNA needed.

Ancestry has added a search feature, allowed raw data file downloads (thank you) and they have updated their ethnicity predictions. The ethnicity predictions are certainly different, dramatically different, but equally as unrealistic. See the Ethnicity Makeovers section for more on this. The search function helps, but what we really need is the chromosome browser, which they have steadfastly avoided promising. Instead, they have said that they will give us “something better,” but nothing has materialized.

I want to take this opportunity, to say, as loudly as possible, that TRUST ME IS NOT ACCEPTABLE in any way, shape or form when it comes to genetic matching. I’m not sure what Ancestry has in mind by the way of “better,” but it if it’s anything like the mediocrity with which their existing DNA products have been rolled out, neither I nor any other serious genetic genealogist will be interested, satisfied or placated.

Regardless, it’s been nearly 2 years now. Ancestry has the funds to do development. They are not a small company. This is obviously not a priority because they don’t need to develop this feature. Why is this? Because they can continue to sell tests and to give shakey leaves to customers, most of whom don’t understand the subtle “untruth” inherent in that leaf match – so are quite blissfully happy.

In years past, I worked in the computer industry when IBM was the Big Dog against whom everyone else competed. I’m reminded of an old joke. The IBM sales rep got married, and on his wedding night, he sat on the edge of the bed all night long regaling his bride in glorious detail with stories about just how good it was going to be….

You can sign a petition asking Ancestry to provide a chromosome browser here, and you can submit your request directly to Ancestry as well, although to date, this has not been effective.

The most frustrating aspect of this situation is that Ancestry, with their plethora of trees, savvy marketing and captive audience testers really was positioned to “do it right,” and hasn’t, at least not yet. They seem to be more interested in selling kits and providing shakey leaves that are misleading in terms of what they mean than providing true tools. One wonders if they are afraid that their customers will be “less happy” when they discover the truth and not developing a chromosome browser is a way to keep their customers blissfully in the dark.

Ancient DNA

This has been a huge year for advances in sequencing ancient DNA, something once thought unachievable. We have learned a great deal, and there are many more skeletal remains just begging to be sequenced. One absolutely fascinating find is that all people not African (and some who are African through backmigration) carry Neanderthal and Denisovan DNA. Just this week, evidence of yet another archaic hominid line has been found in Neanderthal DNA and on Christmas Day, yet another article stating that type 2 Diabetes found in Native Americans has roots in their Neanderthal ancestors. Wow!

Closer to home, by several thousand years is the suggestion that haplogroup R did not exist in Europe after the ice age, and only later, replaced most of the population which, for males, appears to have been primarily haplogroup G. It will be very interesting as the data bases of fully sequenced skeletons are built and compared. The history of our ancestors is held in those precious bones.

Sloppy Science and Sensationalist Reporting

Unfortunately, as DNA becomes more mainstream, it becomes a target for both sloppy science or intentional misinterpretation, and possibly both. Unfortunately, without academic publication, we can’t see results or have the sense of security that comes from the peer review process, so we don’t know if the science and conclusions stand up to muster.

The race to the buck in some instances is the catalyst for this. In other cases, and not in the links below, some people intentionally skew interpretations and results in order to either fulfill their own belief agenda or to sell “products and services” that invariably report specific findings.

It’s equally as unfortunate that much of these misconstrued and sensationalized results are coming from a testing company that goes by the names of BritainsDNA, ScotlandsDNA, IrelandsDNA and YorkshiresDNA. It certainly does nothing for their credibility in the eyes of people who are familiar with the topics at hand, but it does garner a lot of press and probably sells a lot of kits to the unwary.

I hope they publish their findings so we can remove the “sloppy science” aspect of this. Sensationalist reporting, while irritating, can be dealt with if the science is sound. However, until the results are published in a peer-reviewed academic journal, we have no way of knowing.

Thankfully, Debbie Kennett has been keeping her thumb on this situation, occurring primarily in the British Isles.

Citizen Science is Coming of Age

Citizen science has been slowing coming of age over the past few years. By this, I mean when citizen scientists work as part of a team on a significant discovery or paper. Bill Hurst comes to mind with his work with Dr. Doron Behar on his paper, A Copernican Reassessment of the Human Mitochondrial DNA from its Root or what know as the RSRS model. As the years have progressed, more and more discoveries have been made or assisted by citizen scientists, sometimes through our projects and other times through individual research. JOGG, the Journal of Genetic Genealogy, which is currently on hiatus waiting for Dr. Turi King, the new editor, to become available, was a great avenue for peer reviewed publication. Recently, research projects have been set up by citizen scientists, sometimes crowd-funded, for specific areas of research. This is a very new aspect to scientific research, and one not before utilized.

The first paper below includes the Family Tree DNA Lab, Thomas and Astrid Krahn, then with Family Tree DNA and Bonnie Schrack, genetic genealogist and citizen scientist, along with Dr. Michael Hammer from the University of Arizona and others.

Ethnicity Makeovers – Still Not Soup

Unfortunately, ethnicity percentages, as provided by the major testing companies still disappoint more than thrill, at least for those who have either tested at more than one lab or who pretty well know their ethnicity via an extensive pedigree chart.

Ancestry.com is by far the worse example, swinging like a pendulum from one extreme to the other. But I have to hand it to them, their marketing is amazing. When I signed in, about to discover that my results had literally almost reversed, I was greeted with the banner “a new you.” Yea, a new me, based on Ancestry’s erroneous interpretation. And by reversed, I’m serious. I went from 80% British Isles to 6% and then from 0% Western Europe to 79%. So now, I have an old wrong one and a new wrong one – and indeed they are very different. Of course, neither one is correct…..but those are just pesky details…

23andMe updated their ethnicity product this year as well, and fine tuned it yet another time. My results at 23andMe are relatively accurate. I saw very little change, but others saw more. Some were pleased, some not.

The bottom line is that ethnicity tools are not well understood by consumers in terms of the timeframe that is being revealed, and it’s not consistent between vendors, nor are the results. In some cases, they are flat out wrong, as with Ancestry, and can be proven. This does not engender a great deal of confidence. I only view these results as “interesting” or utilize them in very specific situations and then only using the individual admixture tools at www.Gedmatch.com on individual chromosome segments.

As Judy Russell says, “it’s not soup yet.” That doesn’t mean it’s not interesting though, so long as you understand the difference between interesting and gospel.

Genetic Genealogy Education Goes Mainstream

With the explosion of genetic genealogy testing, as one might expect, the demand for education, and in particular, basic education has exploded as well.

I’ve written a 101 series, Kelly Wheaton wrote a series of lessons and CeCe Moore did as well. Recently Family Tree DNA has also sponsored a series of free Webinars. I know that at least one book is in process and very near publication, hopefully right after the first of the year. We saw several conferences this year that provided a focus on Genetic Genealogy and I know several are planned for 2014. Genetic genealogy is going mainstream!!! Let’s hope that 2014 is equally as successful and that all these folks asking for training and education become avid genetic genealogists.

A Thank You in Closing

I want to close by taking a minute to thank the thousands of volunteers who make such a difference. All of the project administrators at Family Tree DNA are volunteers, and according to their website, there are 7829 projects, all of which have at least one administrator, and many have multiple administrators. In addition, everyone who answers questions on a list or board or on Facebook is a volunteer. Many donate their time to coordinate events, groups, or moderate online facilities. Many speak at events or for groups. Many more write articles for publications from blogs to family newsletters. Additionally, there are countless websites today that include DNA results…all created and run by volunteers, not the least of which is the ISOGG site with the invaluable ISOGG wiki. Without our volunteer army, there would be no genetic genealogy community. Thank you, one and all.

2013 has been a banner year, and 2014 holds a great deal of promise, even without any surprises. And if there is one thing this industry is well known for….it’s surprises. I can’t wait to see what 2014 has in store for us!!! All I can say is hold on tight….

Gene by Gene Genomics Research Center Lab Tour

Posted on November 14, 2013 by Roberta Estes

Both before and after the 9th Annual Family Tree DNA International Conference for Genetic Genealogy this past weekend, Max Blankfeld and Bennett Greenspan were gracious enough to allow interested administrators to visit and tour their labs. I’ve toured other DNA labs, but their lab has very cool leading edge equipment. It was a wonderful treat to see it in action.

What I didn’t have was my “good” camera, so I’m sharing my iPhone photos.

I went on the last tour available and there were only a few of us, so it an excellent opportunity to see things up close and personal.

This lab is much larger than I expected. Gene by Gene, in addition to doing all of the DNA processing for Family Tree DNA, DNA Traits and the National Geographic Genographic project, is doing a significant amount of processing for research institutions such as medical schools. While we were there, they were getting ready to prep to run a large order of several hundred exome samples.

But come along with me and you can see for yourself. Bennett gave the tour personally. The bad news is that you’re going to have to rely on my memory, because nothing was allowed in the lab other than our cameras. This was to prevent contamination.

There are other contamination prevention methods as well. Anyone with open toed shoes had to put on booties. Here’s my friend Lisa, who comments periodically on my blog, suiting up for the tour. Next, we were given lab coats to wear inside the facility which we then took off and left by the door, but inside the lab, as we left.

The first stop inside is where they prepare the kits for shipping to customers when an order is placed. They purchase the empty vials, prepare the formula and fill and cap the vials, all automatically.

The “capping” process is the most interesting part and caused them the most consternation in trying to figure out the best way to do this. Bennett said they worried about having a non-tethered lid that might be dropped by the customer, and contaminated, as it turns out, needlessly.

After the kits come back, all but one of the vials goes into storage, shown below, beside the lab, for future testing. This environment does not have to be specially controlled outside of a normal office environment.

The vial that gets opened for the testing undergoes a different process that begins with removing the DNA from the vial and mixing it with a chemical solution that shakes the DNA out of the cells.

This is done overnight in a shaker machine. Reminded me of a paint shaker.

Have you ever seen a custom $600,000 freezer with a robot to retrieve the frozen goods? No? Well, you’re about to. If you have ever tested with Family Tree DNA and there is any DNA left in a vial that has been opened, it’s in this freezer which took the vendor 7 weeks to assemble on site. Capacity is over 550,000 vials and it’s about half full currently.

After the DNA is shaken out of the cells, that mixture has to be handled differently. It has been barcoded during the entire process and the prepared DNA mixture is then put into storage plates which are robotically stored. This retrieval process is initiated when an order is received by the robotic software. Keep in mind that the unit holds more samples than Family Tree DNA has today, in a very regulated deep freeze environment. Depending on what this robotic arm is doing, meaning moving plates around or extracting a specific vial, it changes its own tool on the end of its arm. It knows where every vial is in the freezer. I must admit, my Mom who has been gone since 2006 has DNA there and it made me feel kind of funny to know I was visiting “her.” But my DNA is with hers, along with a whole lot of other family members, so I guess it’s just one big family reunion in there.

After the correct vial is retrieved and the DNA mixture is extracted, the liquid is put onto a “chip” for the autosomal testing. The chip itself is about an inch by maybe 3 inches and holds 12 tests.

The DNA is pipetted into the side and then it is wicked into the chip itself.

Here is a set of two chips loaded and ready to be processed. This means that at total of 24 individual samples are being sequenced. Notice the little grey square to the size of each larger grey square. That tiny grey square is where the DNA mixture it placed and it’s wicked into the larger grey square for processing. We asked how that is done and were told that the technique is part of Illumina’s trade secrets.

Gene by Gene owns several sequencing machines. I know they have at least two Sanger sequencing machines and 4 different sizes and types of Illumina sequencing machines that run chip based tests like the Geno 2, the Family Finder and now the Big Y tests, in addition to the exome and full genome tests. These machines are incredible given that they can run hundreds of tests at a time, which is also how they have dropped the test costs exponentially in the past few years. Some equipment is optimized for running many samples but more slowly and some for running fewer samples but more quickly.

After reading and being automatically scored, the DNA results are reported to the client.

At the end of the lab tour, just outside, is the Customer Service area where the Customer Service Reps work. I’ll tell you what, they had their hands full this week and weekend with their regular call load, a conference and an office full of nosey and interested project administrators.

Of course, during the course of the day, I had to visit the restroom. I’ve always loved Max and Bennett’s sense of humor.

In case you don’t know, the Y chromosome is much smaller than the X, hence, the difference in the signs.

Let’s just say that in light of their new product announcement, the “Big Y,” I did a bit of a structural modification for them:)

Thanks again to Max and Bennett for their hospitality.

Jennifer Zinck also wrote about the Friday lab tour on her blog, Ancestor Central.

2013 Family Tree DNA Conference Day 2

Posted on November 12, 2013 by Roberta Estes

ISOGG Meeting

The International Society of Genetic Genealogy always meets at 8 AM on Sunday morning. I personally think that 8AM meeting should be illegal, but then I generally work till 2 or 3 AM (it’s 1:51 AM now), so 8 is the middle of my night.

Katherine Borges, the Director speaks about current and future activities, and Alice Fairhurst spoke about the many updates to the Y tree that have happened and those coming as well. It has been a huge challenge to her group to keep things even remotely current and they deserve a huge round of virtual applause from all of us for the Y tree and their efforts.

Bennett opened the second day after the ISOGG meeting.

“The fact that you are here is a testament to citizen science” and that we are pushing or sometimes pulling academia along to where we are.

Bennett told the story of the beginning of Family Tree DNA. “Fourteen years ago when the hair that I have wasn’t grey,” he began, “I was unemployed and tried to reorganize my wife’s kitchen and she sent me away to do genealogy.” Smart woman, and thankfully for us, he went. But he had a roadblock. He felt there was a possibility that he could use the Y chromosome to solve the roadblock. Bennett called the author of one of the two papers published at that time, Michael Hammer. He called Michael Hammer on Sunday morning at his home, but Michael was running out the door to the airport. He declined Bennett’s request, told him that’s not what universities do, and that he didn’t know of anyplace a Y test could be commercially be done. Bennett, having run out of persuasive arguments, started mumbling about “us little people providing money for universities.” Michael said to him, “Someone should start a company to do that because I get phone calls from crazy genealogists like you all the time.” Let’s just say Bennett was no longer unemployed and the rest, as they say, is history. With that, Bennett introduced one of our favorite speakers, Dr. Michael Hammer from the Hammer Lab at the University of Arizona.

Session 1 – Michael Hammer – Origins of R-M269 Diversity in Europe

Michael has been at all of the conferences. He says he doesn’t think we’re crazy. I personally think we’ve confirmed it for him, several times over, so he KNOWS we’re crazy. But it obviously has rubbed off on him, because today, he had a real shocker for us.

I want to preface this by saying that I was frantically taking notes and photos, and I may have missed something. He will have his slides posted and they will be available through a link on the GAP page at FTDNA by the end of the week, according to Elliott.

Michael started by saying that he is really exciting opportunity to begin breaking family groups up with SNPs which are coming faster than we can type them.

Michael rolled out the Y tree for R and the new tree looks like a vellum scroll.

Today, he is going to focus on the basic branches of the Y tree because the history of R is held there.

The first anatomically modern humans migrated from Africa about 45,000 years ago.

After last glacial maximum 17,000 years ago, there was a significant expansion into Europe.

Neolithic farmers arrived from the near east beginning 10,000 years ago.

Farmers had an advantage over hunter gatherers in terms of population density. People moved into Northwestern Europe about 5,000 years ago.

What did the various expansions contribute to the population today?

Previous studies indicate that haplogroup R has a Paleolithic origin, but 2 recent studies agree that this haplogroup has a more recent origin in Europe – the Neolithic but disagree about the timing of the expansion.

The first study, Joblin’s study in 2010, argued that geographic diversity is explained by single Near East source via Anaotolia.

It conclude that the Y of Mesololithic hunger-gatherers were nearly replaced by those of incoming farmers.

In the most recent study by Busby in 2012 is the largest study and concludes that there is no diversity in the mapping of R SNP markers so they could not date lineage and expansion. They did find that most basic structure of R tree did come from the near east. They looked at P311 as marker for expansion into Europe, wherever it was. Here is a summary page of Neolithic Europe that includes these studies.

Hammer says that in his opinion, he thought that if P311 is so frequent and widespread in Europe it must have been there a long time. However, it appears that he and most everyone else, was wrong.

The hypothesis to be tested is if P311 originated prior to the Neolithic wave, it would predict higher diversity it the near east, closer to the origins of agriculture. If P311 originated after the expansion, would be able to see it migrate across Europe and it would have had to replace an existing population.

Because we now have sequences the DNA of about 40 ancient DNA specimens, Michael turned to the ancient DNA literature. There were 4 primary locations with skeletal remains. There were caves in France, Spain, Germany and then there’s Otzi, found in the Alps.

All of these remains are between 6000-7000 years old, so prior to the agricultural expansion into Europe.

In France, the study of 22 remains produced, 20 that were G2a and 2 that were I2a.

In Spain, 5 G2a and 1 E1b.

In Germany, 1I G2a and 2 F*.

Otzi is haplogroup G2a2b.

There was absolutely 0, no, haplogroup R of any flavor.

In modern samples, of 172 samples, 94 are R1b.

To evaluate this, he is dropping back to the backbone of haplogroup R.

This evidence supports a recent spread of haplogroup R lineages in western Europe about 5K years ago. This also supports evidence that P311 moved into Europe after the Neolithic agricultural transition and nearly displaced the previously existing western European Neolithic Y, which appears to be G2a.

This same pattern does not extrapolate to mitochondrial DNA where there is continuity.

What conferred advantage to these post Neolithic men? What was that advantage?

Dr. Hammer then grouped the major subgroups of haplogroup R-P3111 and found the following clusters.

U106 is clustered in Germany
L21 clustered in the British Isles
U152 has an Alps epicenter

This suggests multiple centers of re-expansion for subgroups of haplogroup R, a stepwise process leading to different pockets of subhaplogroup density.

Archaeological studies produce patterns similar to the hap epicenters.

What kind of model is going on for this expansion?

Ancestral origin of haplogroup R is in the near east, with U106, P312 and L21 which are then found in 3 European locations.

This research also suggests thatG2a is the Neolithic version of R1b – it was the most commonly found haplogroup before the R invasion.

To make things even more interesting, the base tree that includes R has also been shifted, dramatically.

Haplogroup K has been significantly revised and is the parent of haplogroups P, R and Q.

It has been broken into 4 major branches from several individual lineages – widely shifted clades.

Haps R and Q are the only groups that are not restricted to Oceana and Southeast Asia.

Rapid splitting of lineages in Southeast Asia to P, R and Q, the last two of which then appear in western Europe.

R then, populated Europe in the last 4000 years.

How did these Asians get to Europe and why?

Asian R1b overtook Neolithic G2a about 4000 years ago in Europe which means that R1b, after migrating from Africa, went to Asia as haplogroup K and then divided into P, Q and R before R and Q returned westward and entered Europe. If you are shaking your head right about now and saying “huh?”…so were we.

Here is Dr. Hammer’s revised map of haplogroup dispersion.

Moving away from the base tree and looking at more recent SNPs, Dr. Hammer started talking about some of the findings from the advanced SNP testing done through the Nat Geo project and some of what it looks like and what it is telling us.

For example, the R1bs of the British Isles.

There are many clades under L 21. For example, there is something going on in Scotland with one particular SNP (CTS11722?) as it comprises one third of the population in Scotland, but very rare in Ireland, England and Wales.

New Geno 2.0 SNP data is being utilized to learn more about these downstream SNPs and what they had to say about the populations in certain geographies.

For example, there are 32 new SNPs under M222 which will help at a genealogical level.

These SNPs must have arisen in the past couple thousand years.

Michael wants to work with people who have significant numbers of individuals who can’t be broken out with STRs any further and would like to test the group to break down further with SNPs. The Big Y is one option but so is Nat Geo and traditional SNP testing, depending on the circumstance.

G2a is currently 4-5% of the population in Europe today and R is more than 40%.

Therefore, P312 split in western Eurasia and very rapidly came to dominate Europe

Session 2 – Dr. Marja Pirttivaara – Bridging Social Media and DNA

Dr. Pirttivaara has her PhD in Physics and is passionate about genetic genealogy, history and maps. She is an administrator for DNA projects related to Finland and haplogroup N1c1, found in Finland, of course.

Finland has the population of Minnesota and is the size of New Mexico.

There are 3750 Finland project members and of them 614 are haplogroup N1c1.

Combining the N1c1 and the Uralic map, we find a correlation between the distribution of the two.

Turku, the old capital, was full or foreigners, in Medieval times which is today reflected in the far reaching DNA matches to Finnish people.

Some of the interest in Finland’s DNA comes from migration which occurred to the United States.

Facebook and other social media has changed the rules of communication and allows the people from wide geographies to collaborate. The administrator’s role has also changed on social media as opposed to just a FTDNA project admin. Now, the administrator becomes a negotiator and a moderator as well as the DNA “expert.”

Marja has done an excellent job of motivating her project members. They are very active within the project but also on Facebook, comparing notes, posting historical information and more.

Session 3 – Jason Wang – Engineering Roadmap and IT Update

Jason is the Chief Technology Officer at Family Tree DNA and recently joined with the Arpeggi merger and has a MS in Computer Engineering.

Regarding the Gene by Gene/FTDNA partnership, “The sum of the parts is greater than the whole.” He notes that they have added people since last year in addition to the Arpeggi acquisition.

Jason introduced Elliott Greenspan, who, to most of us, needed no introduction at all.

Elliott began manually scoring mitochondrial DNA tests at age 15. He joined FTDNA in 2006 officially.

Year in review and What’s Coming

4 times the data processed in the past year.

Uploads run 10 times faster. With 23andMe and Ancestry autosomal uploads, processing will start in about 5 minutes, and matches will start then.

FTDNA reinvented Family Finder with the goal of making the user experience easier and more modern. They added photos, profiles and the new comparison bars along with an advanced section and added push to chromosome browser.

Focus on users uploading the family tree. Tools don’t matter if the data isn’t there. In order to utilize the genealogy aspect, the genealogy info needs to be there. Will be enhancing the GEDCOM viewer. New GEDCOMs replace old GEDCOMs so as you update yours, upload it again.

They are now adding a SNP request form so that you can request a SNP not currently available. This is not to be confused with ordering an existing SNP.

They currently utilize build 14 for mitochondrial DNA. They are skipping build 15 entirely and moving forward with 16.

They added steps to the full sequence matches so that you can see your step-wise mutations and decide whether and if you are related in a genealogical timeframe.

New Y tree will be released shortly as a result of the Geno 2.0 testing. Some of the SNPs have mutated as much as 7 times, and what does that mean in terms of the tree and in terms of genealogical usefulness. This tree has taken much longer to produce than they expected due to these types of issues which had to be revised individually.

New 2014 tree has 6200 SNPS and 1000 branches.

Commitment to take genetic genealogy to the next level
Y draft tree
Constant updates to official tree
Commitment to accurate science

If a single sample comes back as positive for a SNP, they will put it on the tree and will constantly update this.

If 3 or 4 people have the same SNP that are not related it will go directly to the tree. This is the reason for the new SNP request form.

Part of the reason that the tree has taken so long is that not every SNP is public and it has been a huge problem.

When they find a new SNP, where does it go on the tree? When one SNP is found or a SNP fails, they have run over 6000 individual SNPs on Nat Geo samples to vet to verify the accuracy of the placement. For example, if a new SNP is found in a particular location, or one is found not to be equivalent that was believe to be so previously, they will then test other samples to see where the SNP actually belongs.

X Matching

Matching differential is huge in early testing. One child may inherit as little as 20% of the X and another 90%. Some first cousins carry none.

X matching will be an advanced feature and will have their own chromosome browser.

End of the year – January 1. Happy New Year!!!

Population Finder

It’s definitely in need of an upgrade and have assigned one person full time to this product.

There are a few contention points that can be explained through standard history.

It’s going to get a new look as well and will be easily upgradeable in the future.

They cannot utilize the National Geographic data because it’s private to Nat Geo.

Bennett – “Committed to an engineering team of any size it takes to get it done. New things will be rolling out in first and second quarter of next year.” Then Bennett kind of sighed and said “I can’t believe I just said that.”

Session 4 – Dr. Connie Bormans – Laboratory Update

The Gene by Gene lab, which of course processes all of the FTDNA samples is now a regulated lab which allows them to offer certain regulated medical tests.

CLIA
CAP
AABB
NYSDOH

Between these various accreditations, they are inspected and accredited once yearly.

Working to decrease turn-around time.

SNP request pipeline is an online form and is in place to request a new SNP be added to their testing menu.

Raised the bar for all of their tests even though genetic genealogy isn’t medical testing because it’s good for customers and increases quality and throughput.

New customer support software and new procedures to triage customer requests.

Implement new scoring software that can score twice as many tests in half the time. This decreases turn-around time to the customer as well.

New projects include improved method of mtDNA analysis, new lab techniques and equipment and there are also new products in development.

Ancient DNA (meaning DNA from deceased people) is being considered as an offering if there is enough demand.

Session 5 – Maurice Gleeson – Back to Our Past, Ireland

Maurice Gleeson coordinated a world class genealogy event in Dublin, Ireland Oct. 18-20, 2013. Family Tree DNA and ISOGG volunteers attended to educate attendees about genetic genealogy and DNA. It was a great success and the DNA kits from the conference were checked in last week and are in process now. Hopefully this will help people with Irish ancestry.

12% of the Americans have Irish ancestry, but a show of hands here was nearly 100% – so maybe Irish descendants carry the crazy genealogist gene!

They developed a website titled Genetic Genealogy Ireland 2013. Their target audience was twofold, genetic genealogy in general and also the Irish people. They posted things periodically to keep people interested. They also created a Facebook page. They announced free (sponsored) DNA tests and the traffic increased a great deal. Today ISOGG has a free DNA wiki page too. They also had a prize draw sponsored by the Ireland DNA and mtdna projects. Maurice said that the sessions and the booth proximity were quite symbiotic because when y ou came out of the DNA session, the booth was right there.

2000-5000 people passed by the booth

500 people in the booth

Sold 99 kits – 119 tests

45 took Y 37 marker tests

56 FF, 20 male, 36 female

18 mito tests

They passed out a lot of educational material the first two days. It appeared that the attendees were thinking about things and they came back the last day which is when half of the kits were sold, literally up until they threatened to turn the lights out on them.

They have uploaded all of the lectures to a YouTube channel and they have had over 2000 views. Of all of the presentation, which looked to be a list of maybe 10-15, the autosomal DNA lecture has received 25% of the total hits for all of the videos.

This is a wonderful resource, so be sure to watch these videos and publicize them in your projects.

Session 6 – Brad Larkin – Introducing Surname DNA Journal

Brad Larkin is the FTDNA video link to the “how to appropriately” scrape for a DNA test. That’s his minute or two of fame! I knew he looked familiar.

Brad began a peer reviewed genetic genealogy journal in order to help people get their project stories published. It’s free, open access, web based and the author retains the copyright.. www.surnamedna.com

Conceived in 2012, the first article was published in January 2013. Three papers published to date.

Encourage administrators to write and publish their research. This helps the publication withstand the test of time.

Most other journals are not free, except for JOGG which is now inactive. Author fees typically are $1320 (PLOS) to $5000 (Nature) and some also have subscription or reader fees.

Peer review is important. It is a critical review, a keen eye and an encouraging tone. This insures that the information is evidence based, correct and replicable.

Session 7 – mtdna Roundtable – Roberta Estes and Marie Rundquist

This roundtable was a much smaller group than yesterday’s Y DNA and SNP session, but much more productive for the attendees since we could give individual attention to each person. We discussed how to effectively use mtdna results and what they really mean. And you just never know what you’re going to discover. Marie was using one of her ancestors whose mtDNA was not the haplogroup expected and when she mentioned the name, I realized that Marie and I share yet another ancestral line. WooHoo!!

Q&A

FTDNA kits can now be tested for the Nat Geo test without having to submit a new sample.

After the new Y tree is defined, FTDNA will offer another version of the Deep Clade test.

Illumina chip, most of the time, does not cover STRs because it measures DNA in very small fragments. As they work with the Big Y chip, if the STRs are there, then they will be reported.

80% of FTDNA orders are from the US.

Microalleles from the Houston lab are being added to results as produced, but they do not have the data from the older tests at the University of Arizona.

Holiday sale starts now, runs through December 31 and includes a restaurant.com $100 gift card for anyone who purchases any test or combination of tests that includes Family Finder.

That’s it folks. We took a few more photos with our friends and left looking forward to next year’s conference. Below, left to right in rear, Marja Pirttivaara, Marie Rundquist and David Pike. Front row, left to right, me and Bennett Greenspan.

See y’all next year!!!

2013 Family Tree DNA Conference Day 1

Posted on November 11, 2013 by Roberta Estes

This article is probably less polished than my normal articles. I’d like to get this information out and to you sooner rather than later, and I’m still on the road the rest of this week with little time to write. So you’re getting a spruced up version of my notes. There are some articles here I’d like to write about more indepth later, after I’m back at home and have recovered a bit.

Max Blankfield and Bennett Greenspan, founders, opened the conference on the first day as they always do. Max began with a bit of a story.

13 years ago Bennett started on a quest….

Indeed he did, and later, Bennett will be relating his own story of that journey.

Someone mentioned to Max that this must be a tough time in this industry. Max thought about this and said, really, not. Competition validates what you are doing.

For competition it’s just a business opportunity – it was not and is not approached with the passion and commitment that Family Tree DNA has and has always had.

He said this has been their best year ever and great things in the pipeline.

One of the big moves is that Arpeggi merged into Family Tree DNA.

10^th Anniversary Pioneer Awards

Quite unexpectedly, Max noted and thanked the early adopters and pioneers, some of which who are gone now but remain with us in spirit.

Max and Bennett recognized the administrators who have been with Family Tree DNA for more than 10 years. The list included about 20 or so early adopters. They provided plaques for us and many of us took a photo with Max as the plaques were handed out.

I am always impressed by the personal humility and gratitude of Max and Bennett, both, to their administrators. A good part of their success is attributed, I’m sure, to their personal commitment not only to this industry, but to the individual people involved. When Max noted the admins who were leaders and are no longer with us, he could barely speak. There were a lot of teary eyes in the room, because they were friends to all of us and we all have good memories.

Thank you, Max and Bennett.

The second day, we took a group photo of all of the recipients along with Max and Bennett.

With that, it was Bennett’s turn for a few remarks.

Bennett says that having their own lab provides a wonderful environment and allows them to benchmark and respond to an ever changing business environment.

Today, they are a College of American Pathologists certified lab and tomorrow, we will find out more about what is coming. Tomorrow, David Mittleman will speak about next generation sequencing.

The handout booklet includes the information that Family Tree DNA now includes over 656,898 records in more than 8,700 group projects. These projects are all managed by volunteer administrators, which in and of itself, is a rather daunting number and amount of volunteer crowd-sourcing.

Session 1 – Amy McGuire, PhD, JD – Am I My Brother’s Keeper?

Dr. McGuire went to college for a very long time. Her list of degrees would take a page or so. She is the Director of the Center for Medical Ethics and Health Policy at Baylor College of Medicine.

Thirteen years ago, Amy’s husband was sitting next to Bennett’s wife on an airplane and she gave him a business card. Then two months ago, Amy wound up sitting next to Max on another airplane. It’s a very small world.

I will tell you that Amy said that her job is asking the difficult questions, not providing the answers. You’ll see from what follows that she is quite good at that.

How is genetic genealogy different from clinical genetics in terms of ethics and privacy? How responsible are we to other family members who share our DNA?

What obligations do we have to relatives in all areas of genetics – both clinical, direct to consumer that related to medical information and then for genetic genealogy.

She referenced the article below, which I blogged about here. There was unfortunately, a lot of fallout in the media.

Identifying Personal Genomes by Surname Inference – Science magazine in January 2013. I blogged about this at the time.

She spoke a bit about the history of this issue.

In 2004, a paper was published that stated that it took only 30 to 80 specifically selected SNPS to identify a person.

2008 – Can you identify an individual from pooled or aggregated or DNA? This is relevant to situations like 911 where the DNA of multiple individuals has been mixed together. Can you identify individuals from that brew?

2005 – 15 year old boy identifies his biological father who was a sperm donor. Is this a good thing or a bad thing? Some feel that it’s unethical and an invasion of the privacy of the father. But others feel that if the donor is concerned about that, they shouldn’t be selling their sperm.

Today, for children conceived from sperm donors, there are now websites available to identify half-siblings.

The movement today is towards making sure that people are informed that their anonymity may not be able to be preserved. DNA is the ultimate identifier.

Genetic Privacy – individual perspectives vary widely. Some individuals are quite concerned and some are not the least bit concerned.

Some of the concern is based in the eugenics movement stemming from the forced sterilization (against their will) of more than 60,000 Americans beginning in 1907. These people were considered to be of no value or injurious to the general population – meaning those institutionalized for mental illness or in prison.

1927 – Buck vs Bell – The Supreme court upheld forced sterilization of a woman who was the third generation institutionalized female for retardation. “Three generations of imbeciles is enough.” I must say, the question this leaves me with is how institutionalized retarded women got pregnant in what was supposed to be a “protected” environment.

Hitler, of course, followed and we all know about the Holocaust.

I will also note here that in my experience, concern is not rooted in Eugenics, but she deals more with medical testing and I deal with genetic genealogy.

The issues of privacy and informed consent have become more important because the technology has improved dramatically and the prices have fallen exponentially.

In 2012, the Nonopore OSB Sequencer was introduced that can sequence an entire genome for about $1000.

Originally, DNA data was provided in open access data bases and was anonymized by removing names. The data base from which the 2013 individuals were identified removed names, but included other identifying information including ages and where the individuals lived. Therefore, using Y-STRs, you could identify these families just like an adoptee utilizes data bases like Y-Search to find their biological father.

Today, research data bases have moved to controlled access, meaning other researchers must apply to have access so that their motivations and purposes can be evaluated.

In a recent medical study, a group of people in a research study were informed and educated about the utility of public data bases and why they are needed versus the tradeoffs, and then they were given a release form providing various options. 53% wanted their info in public domain, 33 in restricted access data bases and 13% wanted no data release. She notes that these were highly motivated people enrolled in a clinical study. Other groups such as Native Americans are much more skeptical.

People who did not release their data were concerned with uncertainly of what might occur in the future.

People want to be respected as a research participant. Most people said they would participate if they were simply asked. So often it’s less about the data and more about how they are treated.

I would concur with Dr. McGuire on this. I know several people who refused to participate in a research study because their results would not be returned to them personally. All they wanted was information and to be treated respectfully.

What the new genetic privacy issues are really all about is whether or not you are releasing data not just about yourself, but about your family as well. What rights or issues do the other family members have relative to your DNA?

Jim Watson, one of the discoverers of DNA, wanted to release his data publicly…except for his inherited Alzheimer’s status. It was redacted, but, you can infer the “answer” from surrounding (flanking regions) DNA. He has two children. How does this affect his children? Should his children sign a consent and release before their father’s genome is published, since part of it is their sequence as well? The academic community was concerned and did not publish this information. Jim Watson published his own.

There is no concrete policy about this within the academic community.

Dr McGuire then referenced the book, “The Immortal Life of Henrietta Lacks”. Henrietta Lacks was a poor African-American woman with ovarian cancer. At that time, in the 1950s, her cancer was considered “waste” and no release was needed as waste could be utilized for research. She was never informed or released anything, but then they were following the protocols of the time. From her cell line, the HeLa cell line, the first immortal cell line was created which ultimately generated a great deal of revenue for research institutes. The family however, remained impoverished. The genome was eventually fully sequenced and published. Henrietta Lacks granddaughter said that this was private family information and should never have been published without permission, even though all of the institutions followed all of the protocols in place.

So, aside from the original ethics issues stemming from the 1950s – who is relevant family? And how does or should this affect policy?

How does this affect genetic genealogy? Should the rules be different for genetic genealogy, assuming there are (will be) standard policies in place for medical genetics? Should you have to talk to family members before anyone DNA tests? Is genetic information different than other types of information?

Should biological relatives be consulted before someone participates in a medical research study as opposed to genetic genealogy? How about when the original tester dies? Who has what rights and interests? What about the unborn? What about when people need DNA sequencing due to cancer or another immediate and severe health condition which have hereditary components. Whose rights trump whose?

Today, the data protections are primarily via data base access restrictions.

Dr. Mcguire feels the way to protect people is through laws like GINA (Genomic Information Nondiscrimination Act) which protects people from discrimination, but does not reach to all industries like life insurance.

Is this different than people posting photos of family members or other private information without permission on public sites?

While much of Dr. McGuire’s focus in on medical testing and ethics, the topic surely is applicable to genetic genealogy as well and will eventually spill over. However, I shudder to think that someone would have to get permission from their relatives before they can have a Y-line DNA test. Yes, there is information that becomes available from these tests, including haplogroup information which has the potential to make people uncomfortable if they expected a different ethnicity than what they receive or an undocumented adoption is involved. However, doesn’t the DNA carrier have the right to know, and does their right to know what is in their body override the concerns about relatives who should (but might not) share the same haplogroup and paternal line information?

And as one person submitted as a question at the end of the session, isn’t that cat already out of the bag?

Session 2 – Dr. Miguel Vilar – Geno 2.0 Update and 2014 Tree

Dr. Vilar is the Science manager for the National Geographic’s Genographic Project.

“The greatest book written is inside of us.”

Miguel is a molecular anthropologist and science writer at the University of Pennsylvania. He has a special interest in Puerto Rico which has 60% Native mitochondrial DNA – the highest percentage of Native American DNA of any Caribbean Island.

The Genographic project has 3 parts, the indigenous population testing, the Legacy project which provides grants back to the indigenous community and the public participation portion which is the part where we purchase kits and test.

Below, Dr. Vilars discussed the Legacy portion of the project.

The indigenous population aspect focuses both on modern indigenous and ancient DNA as well. This information, cumulatively, is used to reconstruct human population migratory routes.

These include 72,000 samples collected 2005-2012 in 12 research centers on 6 continents. Many of these are working with indigenous samples, including Africa and Australia.

42 academic manuscripts and >80 conference presentations have come forth from the project. More are in the pipeline.

Most recently, a Science paper was published about the spread of mtDNA throughout Europe across the past 5000 years. More than 360 ancient samples were collected across several different time periods. There seems to be a divide in the record about 7000 years ago when several disappear and some of the more well known haplogroups today appear on the scene.

Nat Geo has funded 7 new scientific grants since the Geno 2.0 portion began for autosomal including locations in Australia, Puerto Rico and others.

Public participants – Geno 1.0 went over 500,000 participants, Geno 2.0 has over 80,000 participants to date.

Dr. Vilar mentioned that between 2008 and today, the Y tree has grown exponentially. That’s for sure. “We are reshaping the tree in an enormous way.” What was once believed to very homogenous, but in reality, as it drills down to the tips, it’s very heterogenous – a great deal of diversity.

As anyone who works with this information on a daily basis knows, that is probably the understatement of the year. The Geno 2.0 project, the Walk the Y along with various other private labs are discovering new SNPs more rapidly than they can be placed on the Y tree. Unfortunately, this has led to multiple trees, none of which are either “official” or “up to date.” This isn’t meant as a criticism, but more a testimony of just how fast this part of the field is emerging. I’m hopeful that we will see a tree in 2014, even if it is an interim tree. In fact, Dr. Vilars referred to the 2014 tree.

Next week, the Nat Geo team goes to Ireland and will be looking for the first migrants and settlers in Ireland – both for Y DNA and mitochondrial DNA. Dr. Vilars says “something happened” about 4000 years ago that changed the frequency of the various haplogroups found in the population. This “something” is not well understood today but he feels it may be a cultural movement of some sort and is still being studied.

Nat Geo is also focused on haplogroup Q in regions from the Arctic to South America. Q-M3 has also been found in the Caribbean for the first time, marking a migration up the chain of islands from Mexico and South America within the past 5,000 years. Papers are coming within the next year about this.

They anticipate that interest will double within the next year. They expect that based on recent discoveries, the 2015 Y tree will be much larger yet. Dr. Michael Hammer will speak tomorrow on the Y tree.

Nat Geo will introduce a “new chip by next year.” The new Ireland data should be available on the National Geographic website within a couple of weeks.

They are also in the process up updating the website with new heat maps and stories.

Session 3 – Matt Dexter – Autosomal Analyses

Matt is a surname administrator, an adoptee and has a BS in Computer Science. Matt is a relatively new admin, as these things go, beginning his adoptive search in 2008.

Matt found out as a child that he was adopted through a family arrangement. He contacted his birth mother as an adult. She told him who his father was who subsequently took a paternity test which disclosed that the man believed to be his biological father, was not. Unfortunately, his ‘father’ had been very excited to be contacted by Matt, and then, of course, was very disappointed to discover that Matt was not his biological child.

Matt asked his mother about this, and she indicated that yes, “there was another guy, but I told him that the other guy was your father.’ With that, Matt began the search for his biological father.

In order to narrow the candidates, his mother agreed to test, so by process of elimination, Matt now knows which side of his family his autosomal results are from.

Matt covers how autosomal DNA works.

This search has led Matt to an interest in how DNA is passed in general, and specifically from grandparents to grandchildren.

One advantage he has is that he has five children whose DNA he can then compare to his wife and three of their grandparents, inferring of course, the 4^th grandparent by process of elimination. While his children’s DNA doesn’t help him identify his father, it did give him a lot of data to work with to learn about how to use and interpret autosomal DNA. Here, Matt is discussing his children’s inheritance.

Session 4 – Jeffrey Mark Paul – Differences in Autosomal DNA Characteristics between Jewish and Non-Jewish Populations and Implications for the Family Finder Test

Dr.Jeffrey Paul, who has a doctorate in Public Health from John Hopkins, noticed that his and his wife’s Family Finder results were quite different, and he wanted to know why. Why did he, Jewish, have so many more?

There are 84 participants in the Jewish project that he used for the autosomal comparison.

What factors make Ashkenazi Jews endogamous. The Ashkenazi represent 80%of world’sJewish population.

Arranged marriages based on family backgrounds. Rabbinical lineages are highly esteemed and they became very inbred with cousins marrying cousins for generations.

Cultural and legal restrictions restrict Jewish movements and who they could marry.

Overprediction, meaning people being listed as being cousins more closely than they are, is one of the problems resulting from the endogamous population issue. Some labs “correct” for this issue, but the actual accuracy of the correction is unknown.

Jeffrey compared his FTDNA Family Finder test with the expected results for known relatives and he finds the results linear – meaning that the results line up with the expected match percentages for unrelated relatives. This means that FTDNA’s Jewish “correction” seems to be working quite well. Of course, they do have a great family group with which to calibrate their product. Bennett’s family is Jewish.

Jeffrey has downloaded the results of group participants into MSAccess and generates queries to test the hypothesis that Jewish participants have more matches than a non-Jewish control group.

The Jewish group had approximately a total of 7% total non-Ashkenazi Jewish in their Population Finder results, meaning European and Middle Eastern Jewish. The non-Jewish group had almost exactly the opposite results.

Jewish people have from 1500-2100 matches.
Interfaith 700-1100 (Jewish and non)
NonJewish 60-616

Jewish people match almost 33% of the other Jewish people in the project. Jewish people match both Jewish and Interfaith families. NonJewish families match NonJewish and interfaith matches.

Jeffrey mentioned that many people have Jewish ancestry that they are unaware of.

This session was quite interesting. This study while conducted on the Jewish population, still applies to other endogamous populations that are heavily intermarried. One of the differences between Jewish populations and other groups, such as Amish, Brethren, Mennonite and Native American groups is that there are many Jewish populations that are still unmixed, where most of these other groups are currently intermixed, although of course there are some exceptions. Furthermore, the Jewish community has been endogamous longer than some of the other groups. Between both of those factors, length of endogamy and current mixture level, the Jewish population is probably much more highly admixed than any other group that could be readily studied.

Due to this constant redistribution of Jewish DNA within the same population, many Jewish people have a very high percentage of distant cousin relationships.

For non-Jewish people, if you are finding match number is the endogamous range, and a very high number of distant cousins, proportionally, you might want to consider the possibility that some of your ancestors descend from an endogamous population.

Unfortunately, the photo of Dr. Paul was unuseable. I knew I should have taken my “real camera.”

Session 5 – Finding Your Indian Prince(ss) Without Having to Kiss Too Many Frogs

This was my session, and I’ll write about it later.

Someone did get a photo, which I’ve lifted from Jennifer Zinck’s great blog (thank you Jennifer), Ancestor Central. In fact, you can see her writeup for Day 1 here and she is probably writing Day 2’s article as I type this, so watch for it too.

Session 6 – Roundtable – Y-SNPs, hosted by Roberta Estes, Rebekah Canada and Marie Rundquist

At the end of the day, after the breakout sessions, roundtable discussions were held. There were several topics. Rebekah Canada, Marie Rundquist and I together “hostessed” the Y DNA and SNP discussion group, which was quite well attended. We had a wide range of expertise in the group and answered many questions. One really good aspect of these types of arrangements is that they are really set up for the participants to interact as well. In our group, for example, we got the question about what is a public versus a private SNP, and Terry Barton who was attending the session answered the question by telling about his “private” Barton SNPs which are no longer considered private because they have now been found in three other surname individuals/groups. This means they are listed on the “tree.” So sometimes public and private can simply be a matter of timing and discovery.

Here’s Bennett leading another roundtable discussion.

Session 7 – Dr. David Mittleman

Dr. Mittleman has a PhD in genetics, is a professor as well as an entrepreneur. He was one of the partners in Arpeggi and came along to Gene by Gene with the acquisition. He seems to be the perfect mixture of techie geek, scientist and businessman.

He began his session by talking a bit about the history of DNA sequencing, next generation sequencing and a discussion about the expectation of privacy and how that has changed in the past few years with Google which was launched in 2006 and Facebook in 2010.

David also discussed how the prices have dropped exponentially in the past few years based on the increase in the sophistication of technology. Today, Y SNPs individually cost $39 to test, but for $199 at Nat Geo you can test 12,000 Y SNPs.

The WTY test, now discontinued tsted about 300,000 SNPs on the Y. It cost between $950 (if you were willing to make your results public) and $1500 (if the results were private,)

Today, the Y chromosome can be sequenced on the Illumina chip which is the same chip that Nat Geo used and that the autosomal testing uses as well. Family Tree DNA announced their new Big Y product that will sequence 10 million positions and 25,000 known SNPs for an introductory sale price of $495 for existing customers. This is not a test that a new customer would ever order. The test will normally cost $695.

ISOGG Reception

The ISOGG reception is one of my favorite parts of the conference because everyone comes together, can sit in groups and chat, and the “arrival” adrenaline has worn off a bit. We tend to strategize, share success stories, help each other with sticky problems and otherwise have a great time. We all bring food or drink and sometimes pitch in to rent the room. We also spill out into the hallways where our impromptu “meetings” generally happen. And we do terribly, terribly geeky things like passing our iPhones around with our chromosome painting for everyone to see. Do we know how to party or what???

Here’s Linda Magellan working hard during the reception. I think she’s ordering the Big Y actually. We had several orders placed by admins during the conference.

We stayed up way too late visiting and the ISOGG meeting starts at 8 AM tomorrow!

Supreme Court Decision – Genes Can’t Be Patented

Posted on June 13, 2013 by Roberta Estes

In a victory for consumers, patients, researchers and women, the Supreme Court today returned a decision that human genes cannot be patented.

Their decision states that DNA ”is a product of nature and not patent eligible merely because it has been isolated.”

This case was a result of a suit against Myriad Genetics, a company that was granted patents for isolating two human genes, known as BRCA1 and BRCA2, both of which are well known breast cancer genes, recently brought to light by Angelina Jolie’s decision to have preventative mastectomys after both the gene and related breast cancer were found to be prevalent in her family. Shortly after that decision and surgery, Jolie’s aunt died of breast cancer.

While companies cannot patent the genes themselves, they can develop treatments and hopefully, cures, and those can be patented. Synthetic genes created are also eligible for patents. Myriad wasn’t the only company to do this. The government has issued patents to over 4000 genes to both companies and universities.

The patenting of genes made it impossible for other competing companies who could test for the gene technically to do so. In other words, it artificially created a sole supplier situation where only one company could provide the test for that gene, and therefore could set the price wherever they wanted. Jolie revealed that the cost of screening for those two genes alone was $3000, a cost prohibitive to many women. However, the actual cost of the testing is significantly less. I was wondering just how much less, then the answer arrived in my inbox.

I know that Gene by Gene, through its division, DNA Traits has the capability to offer this test and has been selling it internationally since 2012. Bennett Greenspan, president of Gene by Gene has discussed this with me privately, and how terribly it pained him not to be able to do this testing to help people within the US. Bennett shared some pretty profound thoughts about the unfair situation this created.

I was just getting ready to call Bennett, when less than 6 hours after the Supreme Court decision, I received an e-mail from Gene by Gene, which contained the answer – $995. So the actual cost to the American consumer is only about one third to one quarter of what they were being charged as a result of the patent.

Today’s Supreme Court decision is truly a victory for patients, consumers, researchers, women and all US citizens. Below is the content of the e-mail I received from Gene by Gene announcing the ability for DNATraits to sell the BRCA test in the US.

In effort to increase access to potentially lifesaving BRCA1 and BRCA2 tests, DNATraits can now offer tests for $995, a fraction of the cost of similar tests prior to the court decision

HOUSTON — Jun. 13, 2013 – Thanks to today’s U.S. Supreme Court decision opening the door to greater access to genetic medicine by American patients and their health care providers, testing for genes specifically linked to breast, ovarian and other cancers will now be more widely available and at a lower cost than ever before.

DNATraits, a division of Houston-based genomics and genetics testing company Gene By Gene, Ltd., announced today that it will offer testing for the BRCA1 and BRCA2 genes in the United States for $995. Prior to today’s unanimous Supreme Court ruling, when exorbitant licensing fees kept DNATraits and others from offering BRCA gene tests in the United States, the cost for such tests was around $4,000.

“We’re pleased to make this important testing more widely available and accessible in the United States,” said Gene By Gene President Bennett Greenspan. “Our highly automated CLIA-registered lab and efficient processes enable us to make genetic and genomic testing more affordable and accessible to more individuals, in the U.S. and worldwide. And that’s our company’s mission, in a nutshell.”

The company’s announcement about the tests, which gained national attention when actress Angelina Jolie courageously revealed in May that being a BRCA1 carrier was among the factors in her decision to have a preventive double mastectomy, comes after today’s Supreme Court ruling in “Association For Molecular Pathology v. Myriad Genetics.”

“We commend the Supreme Court for opening the door to greater technological innovation and access to genetic tools that promise to save and improve the quality of human lives in the United States,” Greenspan added. “It’s critical that as an industry we are able to continue to engage in healthy competition to drive down the costs of these tests – because as more individuals have access to and undergo them, the more information we’ll have about many serious diseases that eventually may lead to cures.”

DNATraits has processed testing for the BRCA1 and BRCA2 genes for individuals living outside the U.S. since 2012. Those genes are processed using traditional Sanger DNA sequencing, which is considered the gold standard for DNA analysis, at the company’s Genomic Research Center in Houston, a CLIA-registered lab which has processed more than 5 million discrete DNA tests from more than 700,000 individuals and organizations globally.

In addition to the BRCA gene tests, DNATraits offers a pre-natal array that covers 111 population specific diseases, as well as other not population-specific diseases, like Duchene Muscular Dystrophy.

Customer Inquiries

Individuals interested in learning more about either the BRCA1 or BRCA2 tests should ask their doctors for more information. They and their health care providers can also visit the company’s website, www.dnatraits.com, or call (713) 868-1438 for more information.

Family Tree DNA Research Center Facilitates Discovery of Ancient Root to Y Tree

Posted on March 26, 2013 by Roberta Estes

The genetic genealogy community has been abuzz for months now with the discovery of the new Root of the Y tree. First announced last fall at the conference for DNA administrators hosted by Family Tree DNA, this discovery has literally changed the landscape of early genetic genealogy and our understanding of the timeframe of the origins of mankind. While it doesn’t make much difference in genetic genealogy in the past few generations, since the adoption of surnames, it certainly makes a difference to all of us in terms of our ancestors and where we came from – our origins. After all, the only difference between current genetic genealogy and the journey of mankind is a matter of generations – and all of our ancestors were there, and survived to reproduce, or we wouldn’t be here.

One of the important aspects of this discovery is the collaboration of citizen scientists with academic institutions and corporations. In this case, the citizen scientist was Bonnie Schrack, a volunteer haplogroup project administrator, Dr. Michael Hammer of the University of Arizona, National Geographic’s Genographic Project, and Thomas Krahn and Astrid Krahn, both with the Gene by Gene Genomics Research Center. Without any one of these players, and Family Tree DNA’s support of projects, this discovery would not have been made. This discovery of the “new root” legitimizes citizen science in the field of genetic genealogy and ushers in a new day in scientific research in which crowd sourced samples, in this case, through Family Tree DNA projects, provide clues and resources for important scientific discoveries.

Today Gene by Gene released a press release about the discovery of the new root. In conjunction, Family Tree DNA has lowered their Y DNA test price to $39 for the introductory 12 marker panel for the month of March, hoping to attract new participants and to eliminate price as a factor. On April 1, the price will increase to $49, still a 50% discount from the previous $99. Who knows where that next discovery lies. Could it be in your DNA?

Family Tree DNA’s Genomics Research Center Facilitates Discovery of Extremely Ancient Root to the Human Y Chromosome Phylogenetic Tree

HOUSTON, March 26, 2013 /PRNewswire/ — Gene By Gene, Ltd., the Houston-based genomics and genetics testing company, announced that a unique DNA sample submitted via National Geographic’s Genographic Project to its genetic genealogy subsidiary, Family Tree DNA, led to the discovery that the most recent common ancestor for the Y chromosome lineage tree is potentially as old as 338,000 years. This new information indicates that the last common ancestor of all modern Y chromosomes is 70 percent older than previously thought.

The surprising findings were published in the report “An African American Paternal Lineage Adds an Extremely Ancient Root to the Human Y Chromosome Phylogenetic Tree” in The American Journal of Human Genetics earlier this month. The study was conducted by a team of top research scientists, including lead scientist Dr. Michael F. Hammer of the University of Arizona, who currently serves on Gene By Gene’s advisory board, and two of the company’s staff scientists, Drs.Thomas and Astrid-Maria Krahn.

The DNA sample had originally been submitted to National Geographic’s Genographic Project, the world’s largest “citizen science” genetic research effort with more than 500,000 public participants to date, and was later transferred to Family Tree DNA’s database for genealogical research. Once in Family Tree DNA’s database, long-time project administrator Bonnie Schrack noticed that the sample was very unique and advocated for further testing to be done.

“This whole discovery began, really, with a citizen scientist – someone very similar to our many customers who are interested in learning more about their family roots using one of our genealogy products,” said Gene By Gene President Bennett Greenspan. “While reviewing samples in our database, she recognized that this specific sample was unique and brought it to the attention of our scientists to do further testing. The results were astounding and show the value of individuals undergoing DNA testing so that we can continue to grow our databases and discover additional critical information about human origins and evolution.”

The discovery took place at Family Tree DNA’s Genomic Research Center, a CLIA registered lab in Houston which has processed more than 5 million discrete DNA tests from more than 700,000 individuals and organizations, including participants in the Genographic Project. Drs. Thomas and Astrid-Maria Krahn of Family Tree DNA conducted the company’s Walk-Through-Y test on the sample and during the scoring process, quickly realized the unique nature of the sample, given the vast number of mutations. Following their initial findings, Dr. Hammer and others joined to conduct a formal study, sequencing ~240 kb of the chromosome sample to identify private, derived mutations on this lineage, which has been named A00.

“Our findings indicate that the last common Y chromosome ancestor may have lived long before the first anatomically modern humans appeared in Africa about 195,000 years ago,” said Dr. Michael Hammer. “Furthermore, the sample, which came from an African American man living in South Carolina, matched Y chromosome DNA of males from a very small area in western Cameroon, indicating that the lineage is extremely rare in Africa today, and its presence in the US is likely due to the Atlantic slave trade. This is a huge discovery for our field and shows the critical role direct-to-consumer DNA testing companies can play in science; this might not have been known otherwise.”

Family Tree DNA recently dramatically reduced the price of its basic Y-DNA test by approximately 50%. By offering the lowest-cost DNA test available on the market today, Gene By Gene and Family Tree DNA are working to eliminate cost as a barrier to individuals introducing themselves to personal genetic and genomic research. They hope that expanding the pool of DNA samples in their database will lead to future important scientific discoveries.
