Genetic Genealogy on TV – Meeting David Wilson

MSNBC will air a documentary tomorrow evening about the journey of 28-year-old African American David Wilson as he discovers his genealogical roots. Wilson uses both traditional genealogical research as well as DNA testing to learn more about his ancestry. Along the way, Wilson meets another David Wilson, a white 62-year-old descendant of the slaveowners who owned the other’s ancestors. From the Meeting David Wilson website:

“Coinciding with the 40th anniversary of the assassination of civil rights leader Dr. Martin Luther King, Jr., MSNBC will premiere “Meeting David Wilson,” the remarkable and inspiring story of a young man’s reconciliation with his ancestors’ history as slaves. The world premiere of “Meeting David Wilson,” on April 11 at 9 p.m. ET will be hosted by “Today” Correspondent Tiki Barber and followed by a 90-minute live discussion of racial issues in America. The live event will be moderated by “NBC Nightly News” Anchor and Managing Editor Brian Williams and held at Howard University in Washington, D.C.”

The younger David Wilson also undergoes DNA testing in hopes to learn more about his ancestry:

“Curious to learn if they have more than a name in common, David tests his DNA. One of the results of this test identifies his African origins. Once this match is made, the lab provides him with a name and location of an African ethnic group and he travels back to Africa to complete his journey.”

To learn more, there is the official Meeting David Wilson Blog, an article on MSNBC, an interesting downloadable press kit (pdf) with a synopsis and pictures (pictures also available online here), other videos. And finally, here is the YouTube trailer:

Navigenics Open For Business

Navigenics, a genome scanning company, officially launches their genome service today – called the “Navigenics Health Compass”, with a cocktail reception in NYC tonight at 6:00PM. Thomas Goetz of Epidemix writes an article in Wired today about some of the differences between Navigenics and other large-scale genome scanning companies.

The launch is also mentioned in an exclusive interview at Genetics and Health with Navigenics’ medical director, Dr. Michael Nierenberg. This piece is the first article in a seven article series, including the future article 6, which discusses some of my favorite things: “Privacy, insurance, GINA, and ethics.” I’ll be sure to link to that article when it comes out. The launch is also discussed over at ScienceRoll.

Genetic Testing Under the Microscope

Genetic Testing Under the Microscope Genetic testing has once again come under the microscope, triggered by an article in the journal Science: “A Case Study of Personalized Medicine.”

In my opinion, adding to the conversation about genetic testing is always a good thing.

That being said, my biggest complaint with many of these articles (especially in the popular media) is that they tend to lump together every test that examines DNA. There are different types of genetic testing with different levels of quality control, interpretation, etc. The results, scientific background, and effects of tests offered by large-scale genome scanning companies, clinical entities, direct-to-consumer companies, and pharmacogenetic companies are not the same. When dealing with a readership that does not have a background in genetics … Click to read more!

The New Y-Chromosome Tree to be Released Tomorrow

A long-anticipated new version of the Y-Chromosome Tree will be released in the journal Genome Research tomorrow (Wednesday, April 2nd). In the paper, scientists from the University of Arizona and Stanford University use recent SNP data and research to reformulate the familiar Y-chromosome tree (see, for example, the current tree at ISOGG). Here is the full text of the press release.  The paper should appear here as soon as it is made available by Genome Research tomorrow.

From the press release:

In an article published online today in Genome Research (www.genome.org), scientists have utilized recently described genetic variations on the part of the Y chromosome that does not undergo recombination to significantly update and refine the Y chromosome haplogroup tree. The print version of this work will appear in the May issue of Genome Research, accompanied by a special poster of the new tree.

Hammer’s group integrated more than 300 new markers into the tree, which allowed the resolution of many features that were not yet discernable, as well as the revision of previous arrangements.

Furthermore, Hammer explains that this work has resulted in the addition of two new major haplogroups, S and T, with novel insights into the ancestry of both. “Haplogroup T, the clade that Thomas Jefferson’s Y chromosome belongs to, has a Middle Eastern affinity, while haplogroup S is found in Indonesia and Oceania.”

Here is the full citation of tomorrow’s paper:

Karafet, T.M., Mendez, F.L., Meilerman, M.B., Underhill, P.A., Zegura, S.L., and Hammer, M.F. New binary polymorphisms reshape and increase resolution of the human Y-chromosomal haplogroup tree. Genome Res. … Click to read more!

The Six Founding Native American Mothers

BeringiaIf you’re interested in DNA, Native American History, or genetic genealogy, then you’re undoubtedly heard of a new paper from PLoS ONE called “The Phylogeny of the Four Pan-American mtDNA Haplogroups: Implications for Evolutionary and Disease Studies.” The authors, from all around the world (including Ugo A. Perego from SMGF and Antonio Torroni from Italy) analyze over 100 complete Native America mtDNA genomes. From the abstract:

“In this study, a comprehensive overview of all available complete mitochondrial DNA (mtDNA) genomes of the four pan-American haplogroups A2, B2, C1, and D1 is provided by revising the information scattered throughout GenBank and the literature, and adding 14 novel mtDNA sequences. The phylogenies of haplogroups A2, B2, C1, and D1 reveal a large number of sub-haplogroups but suggest that the ancestral Beringian population(s) contributed only six (successful) founder haplotypes to these haplogroups.”

All Native American mtDNA can be traced back to five Haplogroups called A, B, C, D, and X. More specifically, Native American mtDNA belongs to sub-haplogroups that are unique to the Americas and not found in Asia or Europe: A2, B2, C1, D1, and X2a (with minor groups C4c, D2, D3, and D4h3). Based on the study, the A2, B2, C1, and D1 groups are estimated to have developed between 18,000 and 21,000 years ago. Since the … Click to read more!

DNA Testing of New York’s New Governor David Paterson

As of Monday the 17th of March, David Paterson will be the Governor of New York State.  Lt. Gov. Paterson recently sat down with Susan Arbetter of WHMT’s NYNOW to discuss the results of his genetic genealogy test results.  Paterson is probably the first governor in the United States to have undergone genetic genealogy testing, and might be the highest government official to do so and then speak openly about it.  These videos are very enjoyable, and it’s interesting to learn more about the future Governor. In the first segment, Arbetter and Paterson discuss some of Paterson’s genealogy.  They also discuss Paterson’s Y-DNA, which is of European origin.  Arbetter writes on her blog: "On the Lt. Governor’s paternal … Click to read more!
