The L.A. Daily News published an article yesterday titled â€œDNA testing helps find lost legacies and cements connections.â€
The article discusses the success some individuals have had using genetic genealogy. For example, Edwin Blancher suspected that his oldest known relative changed his surname from Blanchard to Blancher.DNA testing suggests that he did.
And Doug Miller of California has confirmed that neither his Y chromosome nor his mtDNA are of Native American descent.

Yesterday, the latest edition of Gene Genie was posted at EyeonDNA.Â There’s a lot of interesting articles about a number of different topics in genetics.Â If you have a moment, go check it out.
I have to admit, during the past few months I’ve worried about future of those companies offering genetic genealogy testing (there are at least 31; see the sidebar). I know it’s a funny thing to worry about, but I guess I’m just trying to figure out what the future holds for this type of testing.
My biggest concern, of course, is that whole-genome sequencing will signal the end of many of these companies, at least the ones who do not offer whole-genome sequencing. (By the way, are you sick of hearing about genomic sequencing yet? Lately I feel like I should change the name of the blog to “The Genomic Genealogist” or something like that!). Some might ask, for instance, why one should bother ordering multiple tests once whole-genome sequencing is affordable. And it’s a great question, because we are getting sooo close to that goal!
The Forbes Series â€“ Forbes has an excellent series of articles relating to genomic sequencing and genetic genealogy.It is well-timed and full of interesting things to think about.I highly recommend reading them all!

â€œGenome of DNA Pioneer is Decipheredâ€-This is a write-up by Nicholas Wade in the New York Times.Unfortunately, Mr, Wade used the word â€˜decipheredâ€™ in the article rather than â€˜sequencedâ€™.Iâ€™m not convinced that this was his choice, but heâ€™s getting some flack for it.In any event, it appears that Watsonâ€™s sequence took 2 DVDs rather than just one!Â There’s a write-up at Nature News as well.
Admit it, you’re dying to get your hands on Watson’s genome, aren’t you? Who isn’t?! Yesterday James Watson was handed his sequenced genome on DVD from 454 Life Sciences. There’s a great press release from the Baylor College of Medicine where the ceremony took place.
In a very big day for genetics and human beings alike, Watson was the first person to be handed his entire genetic sequence (for those in the know, Venter only received some or most of his sequence according to most sources).
Amazingly, according to the press release, the genome was sequenced over two months for $1 million. Incredible, considering the Human Genome Project took years and billions of dollars, and even Venter’s project took $300 million.
In case my readers were not aware, the Spring 2007 issue of the Journal of Genetic Genealogy is now available. This free, open-access peer-reviewed journal has been around in the Spring of 2005 and offers recent news and analysis in the field of genetic genealogy. The current issue has the following articles:
A Funny Thing Happened on the Way to Retirement, By T. Whit Athey, editor
Discussion of recent developments in the field as well as nomenclature issues.
Stacking the Deck: Mutation Rate in the mtDNA Coding Region, By Ann Turner
According to the article, “Genetic genealogists, who are obtaining full-sequence mtDNA tests in increasing numbers, are in a position to provide a â€œbiased sampleâ€ for the study of the mutation rate in the coding region.”
Earlier today I wrote about how 23andMe used genetic genealogy to confirm that Warren Buffett and Jimmy Buffett are not recently related via their Y chromosome. I also mentioned that this was a great way to introduce the company (as well as genetic genealogy) to the masses.
This evening I saw a story posted at The Motley Fool entitled “Warren Buffett is No Parrothead.” Similar to the story that I linked to this morning, it appears that the author is not familiar with genetic genealogy:
“However, solving the Buffett mystery illustrates how a stake in 23andMe is a good fit in Google’s portfolio. The one thing that blows me away here is that a simple spit test was enough to uproot a family tree deep enough to find an ancestral link before surnames were even around.
It turns out that 23andMe isnâ€™t just a startup idea thatâ€™s waiting for technology to catch up.In 1999, Fortune Magazine posed the question, â€œAre Jimmy and Warren Buffett Related?â€This week, 23andMe revealed the long-awaited answer, which is that the two Buffetts â€“ well, letâ€™s save that for the end.
Apparently Warren Buffett (finance guru) and Jimmy Buffett (musician), have always wondered if they are related to each other, potentially through a common ancestor who lived in a penal colony in the South Pacific.Earlier this year Anne Wojcicki, the co-founder of 23andMe, asked Jimmy and Warren if they would submit DNA for analysis.According to Warren Buffettâ€™s assistant, he â€œjust kept spitting into a little receptacle, and then we FedExed it.Not very elegant.â€23andMe then did Y chromosome and mtDNA analysis of Warren and Jimmyâ€™s DNA.
In Part I, Part II, and Part III of the “You and the $1000 Genome” series we’ve examined the Archon X PRIZE for Genomics, the International HapMap Project, and the ethical issues associated with both. In this final installment of the series we will examine the potential impact of genomic or SNP sequencing and interpretation on both medicine and genealogy (finally, some genealogy for you patient genealogists out there!).
I believe that whole genome sequencing will have myriad uses. In the paper mentioned in Part III of the series (John A. Robertson, “The $1000 Genome: Ethical and Legal Issues in Whole Genome Sequencing of Individuals (pdf).” 2003 The American Journal of Bioethics 3(3):InFocus), Mr. Robertson suggests that demand for personal genome sequencing outside of the medical context could be quite limited. But that view might fail to take into account uses of genomic information other than identifying or predicting disease, such as the genetic genealogy setting. Very few could have predicted 10 years ago that thousands of genealogists would be submitting their DNA for limited sequencing as they are doing today. If information from whole genome sequencing can be used to analyze genealogy (which it surely will be), then this will create an entire niche that will increase commercial demand outside of the medical context. And this is only one such niche. There might be many many more, some of which will only develop after whole genome sequencing becomes economically available.
As I mentioned recently, James Watson is about to be the first person to have his entire genomic information handed to him. According to this article in Today’s issue of the Observer, Watson “has decided to go ahead and have his entire genome put on the internet this week.” I’m not sure what the Observer used as its source – according to my research Watson hadn’t yet decided what he was going to do with the sequence. Update: A huge story from Newsweek states that Watson has decided to release his entire genome to a NIH database (minus the ApoE gene)!
I hope this gets lots of media coverage. This is a HUGE moment for genetics, one that we will all look back on. And I have to admit, I am very jealous of Watson’s opportunity! Here’s a great article on the subject, well worth a read!Â Here are some highlights from the Observer article:
