Interesting Links From The Genetic Genealogist

dna-stock_phixr.JPGThere is so much to talk about, and so little time to write. So I thought I’d do a round-up post to bring these interesting stories to your attention. I hope you enjoy the following:

Of great significance to genetic genealogists, the Wall Street Journal says that as many as 1 in 25 children are the result of non-paternal events! The number seems very high, but it is based on a 2005 report in the Journal of Epidemiology and Community Health studying families in “the U.S., Europe, Russia, Canada, South Africa and several other countries.”

SNP studies are coming out left and right. The recent studies have examined variation among genomes from numerous populations using SNP chips that examine 600,000 or more SNPs. See more at GenomeWeb News, The Spittoon, and Genetic Future. A great quote comes from a discussion of one of these SNP studies at the terrific Dienekes’ Anthropology Blog:

More 23andMe in the News

image Earlier today I posted about the recent updates to the 23andMe service, including an enhanced Gene Journal section and the new Paternal Ancestry.

To get a much more thorough analysis of these new additions, read David P. Hamilton’s “23andMe makes genomics personal — and slick” at VentureBeat: lifesciences. Hamilton’s articles are always insightful and well-written, and I would highly recommend this one, especially if you are considering a personal genomics service.

Interestingly, Hamilton gives 23andMe’s website high marks over deCODEme’s similar service. Hsien-Hsien Lei at Eye on DNA recently highlighted (in a post entitled “Ann Turner on Personal Genomics Companies 23andMe vs deCODEme“) an article written by genetic genealogist Ann Turner for the GENEALOGY-DNA mailing list in which she compared the services offered by the two companies. Genetic Future picked up Eye on DNA’s post and wrote “Ann Turner compares 23andMe and deCODEme.”

Bryan Sykes Interviewed By The UK’s Telegraph

Anyone who is interested in genetic genealogy has likely heard of Professor Bryan Sykes. Sykes is the founder of the genetic genealogy testing company Oxford Ancestors and author of very influential books such as Blood of the Isles, Adam’s Curse, and The Seven Daughters of Eve.

Sykes was recently interviewed by The Telegraph in an article entitled “Curiosity Drives the Gene Genie to a £1m Turnover.The article mentions that Oxford Ancestors, created in 2000, is currently bringing in £ 1m year (USD $1.96million), which is an increase of 10 times its initial year! There is discussion of Sykes’ upbringing, and the difficulty in commercializing scientific research.

Lastly, Sykes discusses some future directions, including using genetic research to help solve crimes:

GINA – The Genetic Information Nondiscrimination Act

The International Society of Genetic Genealogy (ISOGG) is sponsoring the Save GINA contest. I’ve written about GINA before (see “GINA: A Primer“), which is legislation currently before the Senate the seeks to protect people from discrimination based upon their DNA. The legislation is on hold in the Senate (see my summary here and here).

From the ISOGG contest site:

“GINA is the acronym for “The Genetic Information and Non-Discrimination Act” a bill that has already passed in the U.S. House of Representatives and pending a vote in the Senate except that Senator Tom Coburn of Oklahoma has placed a “hold” on the bill to stall it from being voted upon. You can read the politics involved in the following article in Nature: http://www.nature.com/nature/journal/v451/n7180/full/451745b.html

Family Tree DNA Launches DNATraits, A New DNA Testing Company

image

Bennett Greenspan and Max Blankfeld [I apologize for the previous misspelling of Greenspan’s and Blankfeld’s names] of the genetic genealogy testing company Family Tree DNA have launched a new service called DNATraits to examine a customer’s DNA for evidence of genetic disease. According to the website, DNATraits:

“provides direct-to-consumer genetic data from tests conducted on individual DNA samples. DNATraits offers tests that are broader in scope and less expensive than any in the world, complete with a free consultation with our genetic counselors before testing (optional) and a free consultation after testing (required) to discuss your results.”

DNATraits claims that their service is different from other DNA testing companies, as explained in their comparison page. Notably, the process of returning the results to the consumer appears to be different from some other companies: the DNA results are returned to the “DNATraits medical doctor for review and confirmation” before being sent to a genetic counselor. The customer is then emailed and directed to set up a telephone appointment with the genetic counselor. After the consultation, the customer is given direct access to all their test results.

Genetic Genealogy On The NBC Nightly News

DNA Last week the NBC Nightly News had a three-part special series “Who We Are: The Truth About DNA.

The first video, “Genealogy for Sale” (although it is spelled ‘geneology’!!), is a report from chief science correspondent Robert Bazell. Bazell follows a couple who experience genetic genealogy for the first time. He mentions the use of online websites and databases, including Sorenson and Genetree. In the two minutes of the piece, Bazell does a decent job of highlighting some of the benefits and limitations of genetic genealogy. Just below this video on the main page is a ‘web exclusive’ that continues the couple’s story a bit further.

The second video and third videos are interesting, but are not directly related to genetic genealogy. For anyone that might be interested in more, the Truth About DNA page at MSNBC has a number of interesting links and stories.

The Palatine DNA Project

iStock_000000516280XSmall DNA Projects, often affiliated with a genetic genealogy testing company, are used to coordinate the testing and result analysis of individuals that have the same surname, originate from a common location, or have a comment set of ancestors. For example, I’ve started the Bettinger DNA Project for individuals with the “Bettinger” surname. An example of a project that hopes to analyze the DNA of a common set of ancestors is the Palantine DNA Project.

From Wikipedia:

“Around 1709, the Rhineland-Palatinate region between what is now known as Germany and France was highly contested by each side. At least 13,000 residents left for Holland and London. The English sent them on to America where close to 300 families, led by the Reverend Joshua Kocherthal and the Reverend Johann Frederick Hager, settled in the Hudson River Valley, most noticeably in Saugerties, New York.”

Car manufacturer Buick and the Generation Network’s Ancestry DNA have joined together to offer contest winners the “chance to discover your heritage.” To enter this contest, just go to buick.ancestry.com. You’ll also find a short video there about the PBS series African American Lives 2.

Ten first-place winners with receive a free DNA test kit from Ancestry DNA. An additional 1,000 winners will receive a “Family History Kit” which includes a copy of Family Tree Maker Essentials software, a DVD of African American Lives (not sure if it is this year’s or last year’s) and a copy of “In Search of Our Roots: How 19 Extraordinary African Americans Reclaimed Their Past.” I personally would enjoy either prize.

The Family Tree of Blue-Eyed Individuals

iStock_000003075935XSmall Researchers at the University of Copenhagen suggest that a mutation that arose around 6,000 to 10,000 years ago was inherited by every individual who has blue eyes (original study here). This mutation, located within an intron in a gene called HERC2, reduces the activity of a neighboring gene called OCA2. The researchers located the same mutation in 155 blue-eyed individuals from Denmark as well as in 5 individuals in Turkey and 2 in Jordan. From ScienceDaily:

“‘Originally, we all had brown eyes,’ said Professor Eiberg from the Department of Cellular and Molecular Medicine. ‘But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a ‘switch,’ which literally ‘turned of’ the ability to produce brown eyes.”

Genetic Genealogy is SO Mainstream – More Black History Month Events

black_his08In honor of Black History Month, Anheuser-Busch – through the flagship Budweiser brand – announces a sweepstakes called “Discover Your History” in which a grand-prize winner and three guests will be given a trip to “their ancestral background as determined via genetic testing.” Nine other winners will receive “genetic genealogy testing and ancestral family tree research.”

The testing will be performed by AfricanDNA.com L.L.C., the company founded by Harvard University Professor Henry Louis Gates Jr. in conjunction with Family Tree DNA.

From Anheuser-Busch’s press release:

“One of the most basic human desires is to understand who we are and how our family is woven into the broader, historic context of humanity,” said Johnny Furr Jr., vice president, Community Affairs and Supplier Diversity for Anheuser-Busch, Inc. “We at Budweiser are proud to offer a lucky family the chance to embark on this remarkable journey of discovery. We hope to inspire others to use today’s technology to learn about their ancestors and region of origin.”
