Sorenson Molecular Genealogy Foundation to Protect DNA Samples Using Biomatrica’s Room Temperature Storage

Blaine Bettinger

From today’s press release:

Biomatrica today announced that the Sorenson Molecular Genealogy Foundation (SMGF) will use Biomatrica’s SampleMatrix room temperature storage technology to archive its DNA samples.

SMGF will use the SampleMatrix technology in place of ultra-low-temperature freezers for the long-term storage of all newly collected samples. In addition, SMGF will move its collection of previously archived samples from freezers to room temperature storage.

“SMGF has an extremely valuable collection of DNAs, and we have been very concerned about the long-term storage and preservation of the collection,” said Scott Woodward, executive director of the Sorenson Molecular Genealogy Foundation. “Biomatrica has developed a product that we feel addresses our concerns in a very practical, economical and secure way.” ...

“Can DNA tests help your genealogical inquiries?” in the Asheville Citizen-Times

Blaine Bettinger

An article appears in today’s Asheville Citizen-Times (here) about genetic genealogy. Although brief, the article summarizes the sciences behind Y-DNA and mtDNA testing, and focuses on the use of genetic genealogy to explore the “Clark” surname.

With the famous Thomas Jefferson-Sally Hemmings case, folks began to realize that DNA testing techniques could give answers and break down brick walls as never before.  While DNA will never replace standard research and primary documentation, it can be considered a tool to be used hand in hand with standard research.

A Critique of Genetic Ancestry Testing in Science Magazine

Blaine Bettinger 9 Comments

Gold StandardFive bioethicists have published a paper in today’s issue of Science – The Illusive Gold Standard in Genetic Ancestry Testing (paid subscription required) – calling for government regulation of genetic ancestry testing (aka genetic genealogy). There is an accompanying press release: Stanford Bioethicist and Colleagues Call for Federal Regulation of Genetic Ancestry Testing (another press release is available here).

Overall Thoughts

I highly respect the work of these authors, and I appreciate their efforts to educate the public about these issues. I do, however, wonder why the article was published in Science. The article mostly rehashes arguments found in a number of other articles (including from a very similar 2007 Science article (link) with some of the same authors) without adding any new research or supporting evidence. This is my greatest criticism of this and related articles – much of the hypothesis rests on anecdotal evidence without any corresponding research for support (such as objective social research with genetic ancestry testing customers). ...
