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….

Native Americans, Neanderthal and Denisova Admixture

Posted on December 26, 2013 by Roberta Estes

Recently, a Neanderthal toe bone yielded enough DNA to sequence the full genome of the woman whose remains were found in the Denisova Cave in the Altai Mountains, shown above. This information was published in the Journal Nature in an article titled “The complete genome sequence of a Neanderthal from the Altai Mountains” by Prufer et al. I wrote about what was found here, but it wasn’t until I really read the 200+ pages of supplemental information that I found additional buried information.

The article itself talks about some of the findings relative to Native Americans, but the supplemental information provides additional detail and the supporting charts.

In the paper, the Mixe and the Karitiana people of Mexico and Brazil, respectively were most often used to represent Native Americans. There are about 90,000 Mixe language speakers alive today, so their population is not small. However, the Karitiana are just the opposite, with only about 320 people in a very remote region of Brazil. The Karitiana shun contact with outsiders. In some parts of this study, additional population groups were used for additional Native samples.

Here’s what the article itself has to say about Neanderthals, Denisovans and Native Americans.

Denisovan gene flow in mainland Asia

We used the two high-coverage archaic genomes and a hidden Markov model (HMM) to identify regions of specifically Neanderthal and specifically Denisovan ancestry in 13 experimentally phased present-day human genomes (Supplementary Information sections 4 and 13). In the Sardinian and French genomes from Europe we find genomic regions of Neanderthal origin and few or no regions of Denisovan origin. In contrast, in the Han Chinese, the Dai in southern China, and the Karitiana and Mixe in the Americas, we find, in addition to regions of Neanderthal origin, regions that are consistent with being of Denisovan origin (Zscore54.3 excess relative to the Europeans) (Supplementary Information section 13), in agreement with previous analysis based on low-coverage archaic genomes. These regions are also more closely related to the Denisova genome than the few regions identified in Europeans (Supplementary Information section 13). We estimate that the Denisovan contribution to mainland Asian and Native American populations is ,0.2% and thus about 25 times smaller than the Denisovan contribution to populations in Papua New Guinea and Australia. The failure to detect any larger Denisovan contribution in the genome of a 40,000-year-old modern human from the Beijing area suggests that any Denisovan contribution to modern humans in mainland Asia was always quantitatively small. In fact, we cannot, at the moment, exclude that the Denisovan contribution to people across mainland Asia is owing to gene flow from ancestors of present-day people in Oceania after they mixed with Denisovans. We also note that in addition to this Denisovan contribution, the genomes of the populations in Asia and America appear to contain more regions of Neanderthal origin than populations in Europe (Supplementary Information sections 13 and 14).

The fascinating part of this, aside from the fact that Native people also carry both Denisovan and Neanderthal DNA, and that they carry more than Europeans, is that the Denisovan and Neanderthal DNA that they carry is different than that carried by Europeans. In fact, it appears that not all Europeans carry Denisovan DNA and this paper lowers the estimated percentage of Neanderthal for all Europeans.

This difference in the Neanderthal and Denisovan DNA might be able to help solve a long-standing mystery, and that’s whether or not part of the Native population of the Eastern seaboard, and in particular, the far Northeast part of that region, was populated by or admixed with Europeans long before the time of Columbus and other European pre-colonial explorers. This information, of course would have to come from pre-contact burials, but they do exist and with this new information in hand, they might just yield answers never before available.

Dr. Ricki Lewis, in her DNA Science Blog, mentioned something else quite interesting culled from a Christmas Day issue of Nature titled “Sequence variants in SLC16A11 are a common risk factor for type 2 diabetes in Mexico.” In a nutshell, from article introduction, we find this commentary:

“The risk haplotype carries four amino acid substitutions, all in SLC16A11; it is present at ~50% frequency in Native American samples and ~10% in east Asian, but is rare in European and African samples. Analysis of an archaic genome sequence indicated that the risk haplotype introgressed into modern humans via admixture with Neanderthals.”

Ricki extrapolated on this further:

“Researchers determine the degree to which a mutant gene differs from the most common sequence (wild type), then impose a time scale in the form of known mutation rates. The SLC16A11 five-site haplotype is so divergent that it goes back to nearly 800,000 years ago — before our ancestors expanded out of Africa.

The most plausible explanation, unexpected I suspect, seemed to be that the haplotype came from an archaic human – a Neanderthal or Denisovan or their as-yet unnamed contemporaries. And the haplotype indeed shows up in the skeleton of a Neanderthal found in the Denisovan cave in Siberia.”

And so, it seems that the Native American people today indeed inherited their propensity for type 2 diabetes from their ancient Neanderthal ancestors who lived in the Altai Mountains. It also appears that this genetic predisposition did not carry forward to Europe, if indeed this group of Neanderthals was ancestral to Europeans at all.

Sequencing of Neanderthal Toe Bone Reveals Unknown Hominin Line

Posted on December 22, 2013 by Roberta Estes

This week, in the journal Nature, scientists reported on the full sequencing of a Neanderthal toe bone found in the Denisova Cave in the Altai Mountains, the location where the Denisovan skeleton found in 2008 and sequenced earlier this year was also found.

The abstract of the paper, which is behind a paywall, says:

We present a high-quality genome sequence of a Neanderthal woman from Siberia. We show that her parents were related at the level of half-siblings and that mating among close relatives was common among her recent ancestors. We also sequenced the genome of a Neanderthal from the Caucasus to low coverage. An analysis of the relationships and population history of available archaic genomes and 25 present-day human genomes shows that several gene flow events occurred among Neanderthals, Denisovans and early modern humans, possibly including gene flow into Denisovans from an unknown archaic group. Thus, interbreeding, albeit of low magnitude, occurred among many hominin groups in the Late Pleistocene. In addition, the high-quality Neanderthal genome allows us to establish a definitive list of substitutions that became fixed in modern humans after their separation from the ancestors of Neanderthals and Denisovans.

The abstract also includes this graphic from the paper

This sequence is significant because of a number of unique findings.

The skeleton showed physical traits of both Neanderthals and modern humans and is thought to be about 50,000 years old.
Genetic sequencing revealed that this bone belonged to a Neanderthal woman, not a Denisovan, although other Denisovan remains, including one previously sequenced, have been found in this cave.
The closest genetic relative is found in the Mezmaiskaya Cave in the Caucasus Mountains, some 2000+ miles distant. Admittedly, we don’t have a lot of sequenced remains for comparison.
Sequencing revealed a heretofore unknown genetic line of archaic humans. This person obtained from between 2.7 to 5.8 percent of their genome from this unknown line. That percentage is equal to someplace between a great-great-great-grandparent and a great-great-great-great-great-grandparent, assuming only one ancestor was involved. If this unknown human lineage was admixed into the population in multiple individuals, then the trace amounts could be passed around forever, just like the Neanderthal and Denisovan lineages are in Europeans today.
This unknown line could be homo erectus.
There is no evidence that this unknown human lineage interbred with either modern humans or Neanderthals. I would presume this means that this unknown line then bred with the Denisovan group which did not manifest itself in contemporary humans.
This individual was inbred with their parents being closely related, possibly half-siblings or an uncle and niece, or an aunt and nephew or a grandfather and granddaughter or grandmother and grandson. Inbreeding was also common among the woman’s recent ancestors. Another article headline this week pronounced that “Neanderthals Liked Incest” which I found to be offensive. Incest is a highly negatively charged cultural word. In the not so recent past, the practice of inbreeding was perfectly acceptable in European royalty. Furthermore, we have no idea how these people felt about inbreeding, hence the word “liked” is misleading. It could well be that they lived in a small nuclear family group and there were no other choices for partners. There could also be other cultural and selection factors at play here of which we are unaware. For example, perhaps males were more protective of mothers and children to whom they were related than ones where they had no family or group ties – increasing the likelihood of survival of offspring of women to whom the males were related.
At least half of a percent of the Denisovan genome came from Neanderthals, but none of the Denisovan genome has yet been detected in Neanderthals. If this holds, it would imply that our ancestors either bred with Neanderthals and Denisovans separately, or with Denisovans who carried Neanderthal DNA. Given that most Europeans carry more Neanderthal DNA than Denisovan, the second scenario alone is unlikely. It’s also possible that we simply haven’t found Neanderthal’s who did carry Denisovan DNA.
More than 31,000 differences were found between modern humans and Neanderthals and Denisovans, many having to do with brain development.

Dienekes discussed this research in his blog as well. Note his “family tree.”

36 Wives and the Ambassador

Posted on December 21, 2013 by Roberta Estes

A few days ago, I introduced you to Said (pronounced Sigh-eed) Zahouani, “my chauffeur” who lives in London. Jim and I spent a lovely day with Said, who literally “saved the day.” It went from a really bad day to a wonderful treat. Not only did he take us wonderful places, he was just so nice and friendly. We chatted and one topic led to another and we talked, of course, about families and DNA testing. I mean, did you expect anything else?

I love to learn about other cultures, and Said was born in Morocco. The farthest back he knew was about his grandfather, who never left Morocco. I asked him how people in Morocco obtained last names – in relation of course to Y DNA testing – and he told me a fascinating story.

Said’s last name, Zahouani, was his grandfather’s nickname. His grandfather’s nickname meant “womanizer” in Morocco, in the native language.

Why was that his nickname?

Because he had 36 wives.

Yes, I said 36 wives.

No, that is not a typo.

The first thing I thought of was a harem, but no, Said said his grandfather did not have a harem. He was married 36 individual times, to 36 different women attempting to have a male heir. His 36^th wife indeed succeeded in producing such, Said’s father.

Yes, I did the math.

No, I didn’t ask….

But I had questions, so many questions, that I just couldn’t bring myself to ask….like, for example….how did he keep their names straight??? Did he refer to them as “my 25th wife?”

I remember all too clearly my bigamist relative (who got caught, twice no less) whose two wives had the same first name and the terrible jokes the rest of the family made about that….but I digress.

What did Said’s grandfather’s family think of this? Were there female children? Did he get divorced between marriages? Moroccan culture permits multiple marriages, generally up to 4, so long as the first wife gives permission, although today this traditional way-of-life has pretty much gone by the wayside in Morocco. And 36 is a lot more than 4.

Which begs another question. How, simply how, does one convince 36 women to do this? I mean, maybe the first and second weren’t too tough….but how do you convince number 20, or 30, or 36?

I don’t know the answer to that, but I figure either Said’s grandfather was phenomenally wealthy, incredibly handsome or unbelievably silver-tongued, or maybe all three.

No, I simply couldn’t bring myself to ask. But just think of how many people he might be able to DNA test.

Needless to say, I was fascinated, both with the idea of 36 wives and also by the fact that his grandfather’s nickname then became the family surname. I thought I had heard just about every type of surname acquisition story in existence by now, but I was obviously wrong!

Said is fascinated too. He is going back to Morocco to find out more about his ancestors and to preserve this heritage for his children and grandchildren. He is interested in DNA testing as well and what additional ancestral information it might hold. I told him I’m guessing he’s E1b1b1 – given that this haplogroup is so prevalent in Morocco – but he might be something else quite exotic. I’d love to know, and so would he.

So I left Said that evening, thinking I would never see him again. We exchanged cards. However, that was not the case, because a few days later, our plans for getting from London to Dover failed to materialize and not wanting to repeat our London arrival experience, we called Said once again who personally came to drive us to Dover.

He also forgave me for spilling my coffee in his beautiful black Mercedes. The man is a Saint, I swear. And a very gracious one as well. And he didn’t even say Bloody Hell. I, on the other hand, was utterly mortified….

On the way to Dover, we had the opportunity to chat once again, and he took me to another quilt shop too, on the way, even after I spilled my coffee. He had told his friends and family about DNA testing and several are interested.

I had told several people about Said as well.

As I’ve thought about this experience, I’ve realized a few things.

First, we are all ambassadors, whether we realize it or not. What we say and do reflects not only on us, but what we represent – be it a country, a culture, our family, a product, an employer or our passion. We either influence people positively or negatively, all of the time, whether we realize it or not. All of us reading this are ambassadors for genetic genealogy.

Second, there is always an interesting story just waiting to be found. Just ask. After all, how many people do you know whose grandfather had 36 wives???

Third, sometimes a bad day really isn’t a bad day. The day with Said was the best day we had in London. And yes, angels do walk among us, or maybe come to fetch us with their contemporary flying carpet, a black Mercedes.

Said’s and his company are waiting to serve people in London and onto the continent through the Chunnel as well. I’ve suggested to Said that he put together a “Quilt Tour” for London visitors and I’ll be sending him quilt shop information. I introduced him to shop owners as well as we threaded our way through London. I would feel absolutely safe with this man anyplace, with or without my husband. I’d send him to retrieve my daughter, or granddaughter, without a second thought. In fact, I’d insist that he retrieve them! There are 25,000 other cab drivers in London and I’m convinced that not one is as good as Said!!!

So, if you’re planning a visit to London, please call Said. He can turn a bad day into a good one and he will rescue you from whatever pickle you are in. What a wonderful ambassador!

Here is his contact information:

Inside UK Phone: 07 930 133 584

Outside UK Phone: 004479 30 13 35 84

Personal e-mail: saidzahouani@hotmail.com

And no, by the way, this is not a paid commercial. It’s called a “good turn” and paying it forward. You just never know when you might need to be rescued in London. Maybe at the Who Do You Think You Are Conference held each winter???

Maybe, if we are lucky, in a future story we’ll see what Said’s DNA has to say about his ancestors! If you see him, ask him, and tell him the DNA Lady said hello!!! He’s entirely too much a gentleman to say anything about that spilled coffee in his car….but I guarantee you…he’ll remember me!!! Knowing Said, he’ll just smile and say something very gracious:)

Neuroarchaeologists Uncover Iberian Origin of Unusual Alzheimer’s Gene Mutation

Posted on December 13, 2013 by Roberta Estes

Neuroarchaeologists, a term I haven’t heard before, but one we’ll likely hear into the future. Genetics, neurology, genealogy, population genetics….they are all becoming intermixed today solving puzzles that are so complex that just a few years ago, there would have been no prayer of solving them at all.

Take early onset Alzheimers, for example. Keep in mind that this type of Alzheimer’s is only one of several, and much about this disease remains unknown, but for this particular kind of Alzheimer’s disease, this breakthrough is monumental, as is the fact that they can trace it to the Iberian peninsula in the 16^th century.

The history of our ancestors truly is in our genes.

This research was performed at the University of California at Santa Barbara and published this month in Alzheimer’s and Dementia, the Journal of the Alzheimer’s Association. Unfortunately, the academic article is behind a paywall.

Researchers tested more than 100 family members who have the disease. While many predictably showed onset signs of the disease as expected about age 45, some appeared to be protected by as much as a decade. The question was what was protecting these people and does that protective mechanism have relevance for the rest of the people afflicted by Alzheimer’s disease. The answer isn’t yet evident, and research continues, but the process they used to identify this mutation is fascinating.

The team worked with historians and genealogists and using records as old as 1540, managed to track this family, along with their mutation, to a single individual from the Iberian peninsula about the time that Spanish Conquistadors were colonizing Columbia in the early 1500s.

They may call this new field neuroarchaeology, but I think it’s more neurogenealogy, unless they’re excavating graves someplace. But I bet they think neuroarchaeology just sounds more scientific. So, want to get assistance with your genealogy….having a dread disease, or being a politician….either one will help immensely.

23andMe Suspends Health-Related Genetic Tests

Posted on December 6, 2013 by Roberta Estes

We seem to have part of the answer as to what 23andMe will be doing in the short term. Tonight when I went to the 23andMe site, I was greeted with this message.

In case it’s too small to read, it says:

Welcome to 23andMe.

At this time, we have suspended our health-related genetic tests to comply immediately with the U.S. Food and Drug Administration’s directive to discontinue new consumer access during our regulatory review process.

We are continuing to provide you with both ancestry-related genetic tests and raw genetic data, without 23andMe’s interpretation.

If you are an existing customer please click the link below and then go to the health page for additional information. If you are a customer that purchased before 11/22/13, you will still have access to your health-related results.

We remain firmly committed to fulfilling our long-term mission to help people everywhere have access to their own genetic data and have the ability to use that information to improve their lives.

Upon entering the site, please confirm you understand the new changes in our services.

I understand that 23andMe only sells ancestry reports and raw genetic data at this time. I understand 23andMe will not provide health-related reports. However, 23andMe may provide health-related results in the future, dependent upon FDA marketing authorization.

I clicked on “I Understand” and was then taken to the normal sign on screen where their test kit is marketed solely as a genetic genealogy kit, with all mention of health removed.

After signing on, the health button on the main page is gone, but by clicking on “My Results” I can still see the Health Overview and proceed from there. They mentioned additional information on the Health page, but I did not see anything additional. Perhaps more is yet to come.

I do notice that the Research Surveys, Health Profile, and Key Health Recommendations are still present and the health reports/interpretation portions are still there in my account. I was a customer prior to November 22, 2013. But still, I’m surprised that all of the health surveys and questions remain. They are clearly still data-gathering with their existing clients, so obviously hopeful about the FDA resolution.

It appears that the genetic genealogy portion is “safe,” for now, although we don’t know what the future holds for 23andMe as they move through the regulatory process with the FDA. I also wonder if the genetic genealogy marketspace, which has never been a priority to them, can financially sustain them long enough to complete the FDA process. Part of that answer would likely rest upon how long the process takes and the depth of their pockets. So far, they are 5 years and counting, but we don’t know how far along they are in the process. Perhaps additional information will be forthcoming as the deadline of December 13, 15 or 16, depending on how you count, approaches.

I would still suggest downloading your information, just in case, and I wouldn’t wait until the last minute. No matter how well intentioned they are, they may find themselves in a situation where they cannot provide extensive notification about impending changes.

400,000 Year Old DNA from Spain Sequenced

Posted on December 5, 2013 by Roberta Estes

Talk about record shattering. 400,000 year old DNA has now been sequenced, and that quite handily breaks the previous 100,000 year old record. The only problem is that these ancient and archaic people weren’t staying where they were supposed to. Well, that’s “supposed to” according to the story we thought we knew. Obviously, we didn’t know, and ancient DNA is only beginning to tell the story, which isn’t at all like we thought it would be.

Before now, Neanderthals were thought to have settled in the west, meaning Europe primarily, and Denisovans in the East, in Siberia. This is due to where bones have been found and the DNA sequenced from just a few. However, this new find from a cave in Atapuerca, Spain changes all of that. These people were not closely related to Neanderthal, who were later found in Germany, but instead are related to the Denisovans, their remains found some 4000 miles east, per mitochondrial DNA, meaning their direct matrilineal line. However, even though they are related, they are distantly related.

Yesterday the mitochondrial sequence appeared on GenBank, after the release of the paper. According to Ian Logan, this new sequence has just over 500 mutations, about half of which can be matched with Denisovan and the other half are unique. So while the Denisovan and this new sequence do share a maternal ancestor, they are many, many generations distant. Of course, that would be expected, because they are about 350,000 years apart too in terms of time, or a meager 14,000 generations.

What does this mean? The scientists don’t know for sure. Perhaps these Atapuerca Cave people were the ancestors of Denisovans and Neanderthals. Perhaps the Denisovan mitochondrial DNA “washed out” over generations in the Neanderthal or maybe not enough Neanderthal remains have been located and sequenced. Neither Neanderthal nor Denisovan mitochondrial DNA has been found in any living humans or relatively contemporary burials, meaning not outside of Neanderthals and Denisovans. In short, we need more skeletons and more DNA to reveal more information about our ancient ancestors. It opens the possibility that modern humans are but a small sprig on the larger and quite ancient Denisovan/Neanderthal Eurasian tree. We don’t know where modern humans fit in all of this, but according to autosomal genetic results, everyone with either European or Asian heritage carries some of them in all of us, just not the mitochondrial line. We are just beginning this journey of discovery.

For more, access the Science article, Dienekes Anthrolpology Blog and John Hawks blog. The academic article in Nature, A mitochondrial genome sequence of a hominin from Sima de los Huesos, by Meyer et all is behind a paywall.

Now What? – 23andMe and the FDA

Posted on November 26, 2013 by Roberta Estes

I’m sure everyone reading this knows by now that 23andMe has been ordered to stop marketing their DNA test until they comply with previous FDA requirements. I wrote about this earlier. Forbes and several others have weighed in too. The Forbes article is particularly interesting because it is written by Matthew Herper who has covered the FDA for 13 years, so has significant perspective.

Since that time, a firestorm of questions, comments and emotions have been forthcoming, from all directions. As consumers, we feel trapped, caught in the middle of a battle, along with our DNA and results. And sadly, it looks like the battle didn’t have to occur, had 23andMe not ignored the FDA for months after promising results it never delivered. I want to make a couple of comments, then talk about what we, as consumers, can do to prepare for the worst case.

But before I do that, I want to make it very clear that I don’t expect that the worst case scenario will happen. What would that be? 23andMe going out of business. I don’t think that will happen. Even though they, according to the FDA letter, have been negligent in taking care of business and meeting their commitments, they have bright minds and deep pockets….and 15 days to make some sort of conciliatory peace with the FDA. Now I’m not a psychic, but I’m betting that 23andMe headquarters is very busily figuring out all of the things they need to do to put this ugly public chapter behind them. Of course, I could be wrong. This could be the death knell for 23andMe. But I don’t think so, unless they cannot prove the accuracy of their product or they continue to ignore the FDA and fail to meet commitments.

Most of the questions and concerns voiced today by consumers revolve around what will happen to results they already have on the 23andMe website.

There is no reason to think that the results would be removed as long as the website is functional. And their website is their link with the world, so as long as there is 23andMe, there will be a website.

However, the unthinkable has happened before, and 23andMe appears to have been somewhat negligent, so, just in case, what can we do?

1. Print your health results for future reference

On your personal page at 23andMe, select the “Health Overview” option which will then display your elevated risks in each of 4 option categories..

For each of the 4 sections, Health Risks, Inherited Conditions, Traits and Drug Response, there is a blue link at the bottom that says “see all 122 risk reports,” for example. Click on the “see all” link and then simply print the results in each of the 4 categories. If you want to preserve any of the more detailed information in any of the categories, you’ll have to use screen shots.

2. Download your raw data file

Regardless of what you do, or don’t, do with these results, they are yours. After downloading your file, you can simply save the results for later, you can upload them to donation based www.gedmatch.com (when GedMatch is again accepting files, currently estimated to be Dec.1) or you can transfer your file to Family Tree DNA to add your results to their data base and avail yourself of their matches and tools. Right now, the transfer price for either 23andMe or Ancestry files is only $49, which is significantly less than taking a new test at $99 (although the $99 test currently comes with a $100 restaurant.com giftcard.) This gives you the ability to find new matches with people who haven’t tested at 23andMe.

To download your raw data file at 23andMe, sign on to your account, then click on your name in the upper right hand corner of the screen, then on “Browse Raw Data,” then on “Download” in the upper right hand corner of the screen. You’ll then be prompted for your password again and the answer to your secret question. Default will be set to download all data. Leave it that way. You’ll then be asked if you want to open the file or save it. Save it. On a Windows PC, if you don’t direct otherwise, it will be saved in the Downloads directory with a file name where the word “genome_” preceeds the name of the person who tested. Mine is “genome_Roberta_Estes_Full_20131125XXXXXX.

Word of Warning…..

In the past month, 3 of the 5 files I’ve downloaded from 23andMe have been incomplete. I’ve been working with 23andMe for three very frustrating weeks now via e-mail to try to figure out why they are incomplete. So far, I have no answers and I’ve asked if these incomplete files have affected my (and my families) results posted at 23andMe. To date, I’m still getting their standard reply about not being responsible for third party upload sites, which of course is not the question I asked, at all.

A normal 23andMe file will have about 950,000 rows on a spreadsheet, each one representing a single location tested. 23andMe confirmed this number last week. For example, I have 991,000 plus change and my niece has 960,000 plus change. All 3 of the incomplete files have only 574,515 lines each, exactly. And yes, all of them are build 37, and no, they did not test at the same time. I even downloaded them a second, third and fourth time, from different locations using different computers, etc. The files are simply massively incomplete.

These incomplete files cannot be uploaded and utilized by other tools (www.gedmatch.com) or firms, including Family Tree DNA because 40% of the data is missing.

Given this experience, the FDA’s concerns about accuracy have certainly given me pause to reflect….

You can get a good idea as to whether your file is complete or not by the zipped file size when it downloads. The zipped size of the incomplete files is around 5K (4901 to be exact) and the zipped size of the correct files is about 8K (8262 and 8013K to be exact).

Good luck getting help if your file is incomplete. In order to contact the 23andMe customer service department, you have to jump through hoops, stand on your head, pat your stomach and rub your foot at the same time while chewing gum and blowing bubbles. Ok, tiny exaggeration. You really only have to click on “help” then use the “what’s your question” function, and then at the end of that exercize when you don’t receive the answer you need, you can submit a question to them via a form….but not until you go through that process. They’ll get back with you in about a week with a canned reply and then you can begin the back and forth dialogue, with 2-3 day intervals between each e-mail.

3. Contact your matches

If you haven’t contacted all of your matches already, now would be a wonderful time to send invitations. I send a message with each one that includes my e-mail address. Unfortunately, you are forced to utilize the in-house messaging system at 23andMe, so unless you’ve exchanged e-mail addresses with your matches, if the 23andMe system goes away, you have no way to contact anyone ever again.

4. Send your e-mail address to all of the people who have already accepted match requests

Obviously, this is for the same reason. Otherwise, your ability to communicate with your matches will disappear if the website does. Personally I far prefer e-mail rather than the messaging system anyway, so this is not a wasted opportunity.

I want to say, again, that I don’t believe that anything horrible will happen to 23andMe. I don’t want to be an alarmist. They have deep pockets and lots of lawyers. They may get a slap on the hand, but in the long run, I think they’ll be around in one form or another, assuming, of course, that they can prove their results are accurate. I do have to ask myself why 23andMe has been unable to do this in 5 years. Was it just not a priority, corporate arrogance, or is there a real problem lurking? However, as for my data and results, better safe than sorry, and we should probably be taking these steps anyway. I’m glad I downloaded the data files for my family, because it has exposed a problem that I otherwise wouldn’t have known existed. Hopefully, I’ll still have time to get it resolved.

FDA Orders 23andMe to Discontinue Testing

Posted on November 25, 2013 by Roberta Estes

Never, ever, mess with the big guns.

The FDA has issued a cease and desist letter to 23andMe and ordered the firm to stop selling their DNA tests based on concerns of accuracy, failure to comply with FDA requirements and the fact that they are providing “specific health recommendations” to their clients.

Here is the actual letter.

“The Food and Drug Administration (FDA) is sending you this letter because you are marketing the 23andMe Saliva Collection Kit and Personal Genome Service (PGS) without marketing clearance or approval in violation of the Federal Food, Drug and Cosmetic Act.

Therefore, 23andMe must immediately discontinue marketing the PGS until such time as it receives FDA marketing authorization for the device.”

Normally, the DTC (direct to consumer) test concerns voiced are about people misinterpreting their results, or being frightened by them, without the involvement of a physician. In other words, the move until now has been to force you to visit a doctor to obtain a prescription for this type of test. Of course, the underlying assumption is that the physician will then be available and have expertise in all of the areas that the test covers. That, of course, would mean another follow-up visit, and if all you really wanted was the genealogically relevant results, this would in effect kill that part of their business. In fact, it would probably kill the business entirely, at least under the current marketing model.

The FDA says that the product that 23andMe sells is a medical device, especially since it involves important medical information such as the detection of the BRCA-related breast cancer gene and sensitivity to the blood-thinner, warfarin.

Again from the FDA to 23andMe letter:

“Some of the uses for which PGS is intended are particularly concerning, such as assessments for BRCA-related genetic risk and drug responses (e.g., warfarin sensitivity, clopidogrel response, and 5-fluorouracil toxicity) because of the potential health consequences that could result from false positive or false negative assessments for high-risk indications such as these.”

The FDA wants 23andMe to show that these tests are accurate. They are concerned, for example, that the BRCA test provided by 23andMe might provide either a false positive or, even worse, a false negative. A false positive would, of course, provide an individual with a great deal of angst, but they would certainly immediately visit a physician who would prescribe industry-standard follow-up testing where the “false positive” would be caught. A false negative, on the other hand, might mask a deadly situation, delaying detection until too late.

The FDA states that they have been working with 23and Me who has failed to provide the necessary proof. From the looks of this letter, and understanding there are two sides to every story, it looks like 23and Me has not taken the FDA seriously.

“As part of our interactions with you, including more than 14 face-to-face and teleconference meetings, hundreds of email exchanges, and dozens of written communications, we provided you with specific feedback on study protocols and clinical and analytical validation requirements, discussed potential classifications and regulatory pathways (including reasonable submission timelines), provided statistical advice, and discussed potential risk mitigation strategies. As discussed above, FDA is concerned about the public health consequences of inaccurate results from the PGS device; the main purpose of compliance with FDA’s regulatory requirements is to ensure that the tests work.

However, even after these many interactions with 23andMe, we still do not have any assurance that the firm has analytically or clinically validated the PGS for its intended uses, which have expanded from the uses that the firm identified in its submissions. In your letter dated January 9, 2013, you stated that the firm is “completing the additional analytical and clinical validations for the tests that have been submitted” and is “planning extensive labeling studies that will take several months to complete.” Thus, months after you submitted your 510(k)s and more than 5 years after you began marketing, you still had not completed some of the studies and had not even started other studies necessary to support a marketing submission for the PGS. It is now eleven months later, and you have yet to provide FDA with any new information about these tests. You have not worked with us toward de novo classification, did not provide the additional information we requested necessary to complete review of your 510(k)s, and FDA has not received any communication from 23andMe since May. Instead, we have become aware that you have initiated new marketing campaigns, including television commercials that, together with an increasing list of indications, show that you plan to expand the PGS’s uses and consumer base without obtaining marketing authorization from FDA.”

I do believe the FDA has their undivided attention now.

“Therefore, 23andMe must immediately discontinue marketing the PGS until such time as it receives FDA marketing authorization for the device.”

23andMe has 15 days to reply and if they don’t, it could get even uglier.

“Please notify this office in writing within fifteen (15) working days from the date you receive this letter of the specific actions you have taken to address all issues noted above. Include documentation of the corrective actions you have taken. If your actions will occur over time, please include a timetable for implementation of those actions. If corrective actions cannot be completed within 15 working days, state the reason for the delay and the time within which the actions will be completed. Failure to take adequate corrective action may result in regulatory action being initiated by the Food and Drug Administration without further notice. These actions include, but are not limited to, seizure, injunction, and civil money penalties.”

Yep, never mess with the big guns.

In 2010, five different companies, including 23andMe, were served with warning letters when Pathway Genomics announced it would sell its DNA testing product at Walgreen, a plan that never came to fruition after the warning letter. However, this is the first letter of this type to be served on a genomics testing company.

What’s next? We just don’t know. 23andMe has yet to comment, but it looks from this letter like they have limited choices at the moment.

Stay tuned for the next episode of the Wild West in DTC Testing.

Watson, Crick and Spotted Dick

Posted on November 24, 2013 by Roberta Estes

In September, 2013, my husband, Jim, and I visited the British Isles. This trip was planned around various aspects of genealogy and family history – all of which pertain to and were enabled by DNA. I’m going to be sharing portions with you over the next several weeks. These stories will all include DNA, but I’m also going to share other photos with you. The culture, so different from ours, is critically important to understanding our ancestors and these areas are simply beautiful. I’d like to share the entire experience, not just the DNA piece. So I’m inviting you along on my day in London. Come on….we’ll have fun!

I didn’t plan my trip to England with Watson and Crick’s DNA model in mind – that part just kind of evolved, a positive mutation, so to speak.

Jim and I traveled with a family group that indeed did make this trip as a result of DNA – but that is another story for another article, several, in fact. In any case, we weren’t really in charge of where we were staying in London – the tour company took care of that – supposedly. That is a long and sorry saga which I’ll spare you. Let’s just say we weren’t staying at the hotel where we were SUPPOSED to have reservations and the one where we were staying didn’t have air conditioning. It was “broken.” It should have been an aha moment when they handed me a fan when we checked in. At least they did that much. It was very hot.

Suffice it to say, we were close to Hyde Park and Kensington Gardens in London. The idea was that we could take a walk in the park if we wanted to. Flowers often grace every nook and cranny in Europe and the thought of walking and viewing was quite enticing to me. Here is a rose garden in front of a private home near Hyde Park. Just lovely.

The London subway is a bit overwhelming, but it really a good transportation system once you get used to it. You can get places far more quickly by subway than by car on the surface streets.

Still, you stand a high probability of getting lost, at least initially, and it’s pretty intimidating. So we opted to walk when we could. Plus, you get to see a lot more of the area that way. After all, it’s not always the destination. Sometimes, it’s about the journey.

Before we left for London, I searched for the location of the double helix model created by Watson and Crick in 1953 when they discovered DNA. I found that it is in the British Science Museum.

After arrival in London, looking at the map, I discovered that the Science Museum was just on the other side of Hyde Park. I asked and was told that it’s about a 10 minute walk. Have I mentioned never to believe a British person about distances??? It must be genetic – they seem to have a distance judgment impairment gene!

Jim and I set out to walk to the Museum because it seemed like a much better option than three different subway transfers. And after all, it was only 10 minutes away and only drizzling.

We cut across the park and enjoyed the walk and found the museums, further away than we thought, of course. We discovered we were walking on the Princess Diana Memorial walkway, and only after we got home and looked at the photo did I realize that Kensington Palace is behind me.

British parks and gardens are really quite remarkable. There are a lot of them and they have beautiful statues and flowers. This statue is of Prince Albert.

Half an hour or 45 minutes later, we arrived at the Science Museum. It’s quite large, and we asked where the DNA exhibit was located, received directions, and off we went. We were pleased to see that they had an entire exhibit area devoted not to DNA but to what makes people unique. Of course DNA had a prominent position in that exhibit.

The “books of genes” shown above and below is actually the top back of a seat in the museum exhibit.

But we were unable to find the Watson/Crick model. We asked a second time and the guard told us that it was downstairs “by the autos.” We had just come through that area and we didn’t quite believe it would be there, but since it wasn’t where we were, we went to look. Sure enough, in with the 1950s cars and the earliest computers, in a display case but not near anything else similar, we found the double helix model with only a small display description. In fact, we had walked right past it earlier and didn’t notice it because where it is located and how it is displayed is so nondescript.

The helix model itself is kind of difficult to see because it’s small and kind of thin and in the middle of a case with glass on all sides. Jim is trying to get a good picture, but that is almost impossible between its position and the glass and lighting.

The model is constructed using clamps.

It’s actually difficult to see because the aluminum templates, shown below (wiki photo) are on a flat plane so they are being photographed sideways.

I was thrilled to see the model, but saddened that it has been relegated to the section of “vintage cars” when it was the discovery that fueled many of the life-changing medical discoveries of the past few years and nearly everything in the exhibit we had just seen about what makes people unique. If not DNA, then what?

The Crick/Watson double helix model should be the crown jewel of these types of exhibits, not relegated to a place in the footnotes of the 1950s.

The model itself is elegant in that its simplicity belies the complexity of DNA. Yet, that complexity is comprised of simplest of elements combined in the simplest of manners. It’s hard to believe sometimes that we are looking at the recipe for reproduction, for all of life itself.

Here are Crick and Watson with the model.

Of course, we walked back to our hotel, but we took a bit of a different route, past both sets of palace gates (below) and up some side streets.

Glory be, we also found a Starbucks!! We discovered a beautiful old church on Kensington High Street and slipped into the courtyard which is also the cemetery.

It’s hard to believe that just a few feet away on the other side of the fence the London traffic and hustle and bustle are in full force.

This courtyard is a tiny haven of tranquility. Of course, I had to look at the stones to see if there were any familiar names. After all, some of my ancestors were here – however, they weren’t wealthy enough to have stones in churchyards.

Some things have no equivalent here.

Humps, in case you are wondering, are speed bumps. The even more interesting sign was the one that had a picture of two humps, side by side, on the same sign.

We passed this lovely pub that is just so quintessentially English and so beautiful. Surely looks inviting doesn’t it. Want to have an ale???

That evening, we met up with my cousins from New Zealand (more about that later) in The Swan Pub, a very quaint and very English old coaching pub across from Hyde Park, and had an English dinner of what else, fish and chips.

But that wasn’t the end of the adventures. Nosiree….there was what we term as “adventure eating” left to be done. There was Spotted Dick on the dessert menu. Yes, we did, we had to order that and try some. Here’s Jim getting ready to try Spotted Dick. Looks kind of apprehensive doesn’t he. I must admit, it was very, very good.
