The Genetic Genealogist has been accepted to 9rules in the latest round of submissions! I’m honored to be accepted since 9rules is a collection of some of the best blogs around, and I hope that I can live up to the challenge. 9rules has a ‘technology’ community, but not a ‘science’ community; think there’s any chance they’ll start one? More news to come.
And don’t forget that starting next Tuesday I’m starting a great nine-part series of interviews with some of the biggest names in the field of genetic … Click to read more!
Portfolio presents an interesting four-part series by David Ewing Duncan about personal genomics. But before I go on, it is important to realize that this series focuses on personal genomics – analysis of SNPs or sequencing throughout the genome – rather than the much narrower field of genetic genealogy. Although there are some ethical concerns surrounding genetic genealogy, they are not specifically addressed in the series.
Portfolio’s public relations coordinator circulated a summary of the series (I wish I had a PR coordinator!):
In Portfolio.com columnist David Ewing Duncanâ€™s four-part series, â€œYou 2.0,â€ he assess and compares three major websites recently launched that test a personâ€™s DNA for risk-factors for everything from Alzheimerâ€™s Disease and heart attack to drug addiction, an ability to taste bitterness, and ancestry. Is this information ready for prime time? Can it really predict a healthy personâ€™s medical future? Duncan has been tested by 23andme, deCodeme, and Navigenics, and reports on his sometime contradictory and confusing, sometimes funny, and occasionally enlightening results gleaned from these controversial sites that are attempting to bring genetics directly to the people.
Here are the four parts:
- You 2.0: Comparison Shopping For Your Future
- You 2.0: I’m Doomed. Or Not.
- You 2.0: Recreational DNA and Genetic Voyeurism
- You 2.0: Closing the Genetic Gap
Look for David’s Book Later This Summer
According to his website, Duncan is writing a book entitled Experimental Man: One Manâ€™s Intimate Journey Into Himself, Cell by Cell (although I’ve also seen … Click to read more!
For new readers of The Genetic Genealogist, 23andMe is a personal genomics company that offers a service to examine more than 600,000 SNPs throughout an individual’s genome. The information is then used to analyze ancestry (using Y-DNA and mtDNA) and to estimate propensity for disease. For much more info about 23andMe and similar companies, look under “Personal Genomics” on my Featured Articles page.
Today, 23andMe announced on their blog – The Spittoon – the winner of the company’s first ‘Win Your Genome Contest’. The contest was to describe Lilly Mendel, a publicly available but anonymous profile at 23andMe – based upon her genetic information alone. The winner was Mike Cariaso, who previously created a program that analyzes 23andMe SNP data using the growing SNPedia database.

While conducting some online research the other day, I discovered a series of videos about genetic genealogy by Alastair Greenshields, founder of DNA Heritage. The main page contains 6 videos (shown in the list below) that are broken down into 2 to 8 chapters. Since the videos are broken up into chapters, you can can easily skip to the topics that are the most relevant to you.
- Genetic Genealogy Terminology
- Genetic Genealogy Defined
- Tracing My Genetic Heritage
- My Past
- Giving DNA
- Genetic Genealogy Results
There are many other places to find videos about genetic genealogy. Last April I wrote “Ten Videos For Genetic Genealogists“, although only 8 of them are still available. You can also watch videos about DNA here at TGG’s DNA Channel, courtesy of Roots Television. And lastly, Family Tree DNA has videos available on its website.
To give you a preview of the DNA Heritage videos, the first is embedded … Click to read more!

GenomeWeb Daily News published a story on Friday entitled “En route to Neandertal Genome, Researchers Analyze Its Complete Mitochondrial Genome” which revealed the results of recent Neanderthal mtDNA analysis.
On Thursday May 9th, Svante PÃ¤Ã¤bo spoke at the Biology of Genomes meeting at Cold Spring Harbor Laboratory. PÃ¤Ã¤bo’s group, along with 454 Life Sciences, is currently engaged in a project to sequence the Neanderthal genome. The researchers have been able to sequence the complete Neanderthal mtDNA genome with 35-fold coverage. The genome is approximately 16 kilobases long and differs from the CRS at 133 positions. From what I’ve been able to find online, it doesn’t appear that the actual sequencing results have been released to the public. Given current estimates of mtDNA mutation rates, the number of … Click to read more!
The Quantified Self has a follow-up to last week’s post about the reproducibility of SNP testing by 23andMe and deCODEme using Illumina SNP chips (see the Quantified Self’s post and my post). In that post, it was revealed that two comparisons of the 560,000 overlapping SNP results from the two different companies had revealed differences of just 23 locations for one individual and 35 for another.
Soon after last week’s post, one of these individuals – Ann Turner – contacted The Quantified Self with new information that 4 of the SNPs on her list of 35 disagreeing results are also on the other person’s list of 23 disagreeing results (Antonio Oliveira). From Ann’s email to The Quantified Self:
Four of those (rs11149566, rs4458717, rs4660646, and rs754499) were also found in Antonio’s list. That’s more than you would expect by chance.
Interesting results, and as Kelly at TGS points out, “This is why sharing results is so … Click to read more!
I’ve added a new page to the blog called “Featured Articles“. It’s available 24/7 at the top of every page, and contains a categorized list of about 50 of my favorite articles from the last year. These posts are listed under categories including “Popular Articles”, “Personal Genomics”, “Learning About Genetic Genealogy”, “Ethical Issues”, and “Famous DNA”. This easy-to-read format is much easier to navigate than the clumsy “Categories” column in the right sidebar, which returns too many results in no apparent organization. If you’re relatively new to The Genetic Genealogist, you might find some interesting articles that you missed the first time around. Happy … Click to read more!
An Updated Y-DNA Tree at ISOGG
The International Society of Genetic Genealogy (ISOGG) announced today that their Tree Team has completed the 2008 version of the Y-DNA Haplogroup Tree. This revision was a major undertaking, because, as ISOGG states in the version history, “[t]he Karafet et al paper (2008) required a significant revision to the tree and affected all haplogroups.” The reference for this paper is (Karafet T M, Mendez F L, Meilerman M B, Underhill P A, Zegura S L, Hammer M F, (2008).
New Binary Polymorphisms Reshape and Increase Resolution of the Human Y-Chromosomal Haplogroup Tree. Abstract. Genome Research, published online April 2, 2008. Supplementary Material.). From ISOGG’s official release:
MAY 04, 2008 – The 2008 version of the ISOGG Y-DNA Haplogroup Tree is now available online: http://www.isogg.org/tree/. New to the tree is a haplogroup conversion table which is downloadable in MS Word. If you do not have MS Word/MS Office, you can download openoffice.org for a compatible word processing program. Appreciation goes to Richard Kenyon and Charles Moore for their work on compiling this table.
Thanks to Alice Fairhurst and the entire ISOGG Tree Team for all of their hard work and dedication. Added thanks for consultation goes to Jim Wilson, Dennis Garvey, Ken Nordtvedt, and Natalie Myres on various haplogroups. Additional appreciation to Charles Moore (Hg D) and Vincent Vizachero (Hg R) for joining the Content Team Experts.
The site also has a Haplogroup Conversion Table (MS Word) to convert a 2007 haplogroup to an updated 2008 haplogroup.
Updates at FTDNA and ySearch
The Karafet et al paper also resulted in updates to haplogroup designations at Family Tree DNA and ySearch. Users who have … Click to read more!
Although the genome scanning services offered by companies such as 23andMe, deCODEme, and SeqWright have been front and center in the press the last few weeks, I’m sure that the following information will not be included in any of the reports.
Two different sources have concluded that the scanning service offered by 23andMe and deCODEme, who use different types of Illumina SNP Chips, are highly reproducible. In January 2008, Ann Turner compared the results of testing at deCODEme and 23andMe, and concluded that of the 560,163 SNPs that overlapped and had a “call” (meaning there was a measurable result), they agreed on 560,128 and disagreed on 35. Ann wrote in January:
In all of [the disagreed calls], one company would make a homozygous call while the other company made a heterozygous call – there were no cases where they made a completely discordant call. All in all, I’d say that is pretty impressive.
The second analysis comes from Antonio C B Oliveira at Longa Vista, a new blog that appears to have been created to present … Click to read more!
