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.Â 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 GenomeResearch, accompanied by a special poster of the new tree.
Congratulations to RootsTelevision, co-founded by Megan Smolenyak Smolenyak and Marcy Brown, which just won FOUR Telly Awards! The press release is included below. And don’t forget that you can watch RootsTelevision right here at TGG!
RootsTelevision.com Wins Four Telly Awards in Its First Year
PROVO, UT, March 26, 2008 â€“ RootsTelevision.com, an online channel dedicated to all aspects of genealogy and family history, has been recognized in the 29th Annual Telly Awards for four of its original productions. Selected from more than 14,000 shows were â€œDNA Stories: A Tale of Two Fathersâ€ (documentary), â€œHeir Jordan: Extreme Genealogyâ€ (entertainment), â€œRoots Books: Psychic Rootsâ€ (talk show), and â€œFlat Stanleyâ€™s Family Treeâ€ (childrenâ€™s audience).
The Scientific Studies/Papers Page at ISOGG – I’ve been meaning to share this one for a while. The page describes methods for obtaining and reading scientific papers about genetic genealogy (or any other scientific topic, for that matter). This is a helpful resource for anyone who is interested in learning more about the science behind genetic genealogy.
The International Society of Genetic Genealogy (ISOGG) has just launched a new newsletter. The first edition, March 2008, is available here. This edition discusses GINA, a DNA Success Story by Shoshone, a segment called “The Armchair Geneticist: Where Hobby Produces Science”, What’s New in ISOGG, and a Featured DNA Project.
The newsletter is well-written and has some great graphics, so be sure to subscribe to this FREE newsletter (see the bottom of the newsletter for subscription information).
“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.”
MSNBC has a very short article entitled "DNA Testing: Would You Do It?" Last Friday, Linda Avey and Anne Wojcicki – co-founders of 23andMe – were interviewed by NBC News Correspondent Peter Alexander and Today show host Ann Curry to discuss the company. The 7.5 minute video is below:
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 side, like almost 25% of all African Americans, he’s got white progenitors from England, Ireland and Scotland."
An article entitled “Gene Test Kits – Can They Lead To Dating Services” by Annalee Newitz discusses the author’s thoughts on the implications of genome sequencing offered by the number of companies that have sprung up in the past year. As a genetic genealogist who is interested in the intersection of law, science, and ethics, I’m always interested in articles that examine the ethical issues associated with affordable genome sequencing. Unfortunately, this article turned out to have little substance behind some serious accusations.
Newitz begins by mentioning companies 23andMe and deCODEme, both of which recently launched genome scanning services. She then proceeds to her thesis, which is that these services are not only not useful, they are dangerous. She states:
Amy Harmon, a science writer for the New York Times, writes “Gene Map Becomes a Luxury Item,” an article about Knome (know-me), a sequencing company that will return a customer’s entire genomic sequence for $350,000. Knome was co-founded by Harvard professor George Church, who also directs the Personal Genome Project.
Dan Stoicescu is a retired millionaire who has recently become Knome’s first customer, and only the second person in the world to purchase his entire genomic sequence. According to Dr. Stoicescu, he understands that as of today there is little that his sequence will reveal, but he plans to compare the results of new studies to his genome daily, “like a stock portfolio.”
The article also reveals that Illumina is planning “to sell whole genome sequencing to the ‘rich and famous market’ this year,” says chief executive Jay Flatley. This probably won’t pose much of a problem to Knome – the founders have stated that they are only “offering 20 individuals the opportunity to participate in [their] initial launch phase.”
The “Starting a Business” section of the online bizjournals site has an article called “Riding the Revolution” that reviews the success of the entrepreneurs behind the popular Family Tree DNA (who recently launched a new company called DNATraits).
The company was founded in April 2000 and is led by president Bennett Greenspan and chief operating officer Max Blankfeld. As the article details, the company has grown from $2.6 million in revenue in 2004 to $12.2 million in 2006, an incredibly impressive climb.
Part of the article describes the company’s future directions and challenges:
“The best solution to building an infrastructure is to be proactive, Blankfeld says, in areas such as human resources, technology and research and development. ‘We hired and keep hiring good people, whether for customer service or the lab; we invested in state-of-the-art equipment for the lab and we keep developing new tests that will respond to our customers’ needs,’ he says.”
