Senator Edward Kennedy (D-Massachusetts) proposed a piece of legislation before the United States Senate on 1 March 2007 called the â€œLaboratory Test Improvement Act.â€ The Act is proposed as a series of amendments to the Federal Food, Drug, and Cosmetic Act (FFDCA).
Sen. Kennedyâ€™s statement(pdf) before the Senate, found in the Congressional Record from this month, defines his goal as â€œ[ensuring] the quality of clinical tests used every day in hospitals and doctorsâ€™ offices across the country.â€ Additionally, he pointed out that the â€œtests are being used to diagnose illnesses, predict who is most susceptible to specific diseases, and identify persons who carry a genetic disease that they could pass on to their children.â€

The Daily American Newspaper in Somerset, Pennsylvania, recently highlighted a family surname study being conducted through a local forensics company.Â The Eustace/Eustis/Eustice surname Y Chromosome DNA study began in July 2006 and according to the news article the project has tested 80 men in eight countries, a remarkable number.
Ron Eustice, one of the leaders of the study and editor of the Eustice Families Post newsletter emphasizes the importance of DNA to his genealogical research:
â€œMost family historians have spent countless hours poring over genealogical records, trying to connect the dots.Â DNA testing is rapidly establishing itself as the newest and perhaps most reliable tool in the field of family history research. I believe that … Click to read more!
Argus BioSciences, located in Belmont, California, is an up-and-coming company offering DNA sequencing for the study of genetic genealogy. Founded in 2003 by Dr. David Whyte, the company offers mtDNA sequencing and haplotype determination.
Although Argus is currently (as of March 2007) offering only mtDNA testing, all products are being offered at a greatly reduced rate. Sequencing of the hypervariable region (which includes HVR1-3) is offered for only $125.00 (regularly $149). You can compare this price to those offered by other companies in my DNA testing company comparison chart. Additionally, Argus is offering complete sequencing of the entire mitochondrial genome (16, 569 bases) for $345 (regularly $695). The company will also accept four monthly payments of $95 to pay for … Click to read more!
The last time I counted there are at least 21 unique companies offering DNA testing for genealogical purposes, either Y-chromosome, mtDNA, or autosomal testing (see the Sidebar to the right for a listing).Â To get a clearer picture of what each company offers I created a master list of every company and the services they offer.Â See here.
While compiling the list I also gathered information about the markers that each Y-chromosome test analyzed.Â See here.Â There are of course the standard markers offered by most companies as well as the markers offered by only a single company.Â What company have you been tested … Click to read more!
AncestryByDNA is a popular genetic test developed by DNAPrint Genomics, Inc. The company offers a variety of genetic testing, including Y-chromosome and mtDNA ancestry. They are most well-known, however, for their two admixture tests. Admixture tests examine SNPs, or single nucleotide polymorphisms, in the 22 autosomal chromosomes in each of our cells. Although every humanâ€™s DNA is 99.9% identical, the 0.1% differences make each one of us unique. Researchers have noticed that people in a particular region often have a mutation in common, one that people in most or all other regions of the world do not have. These usually harmless mutations, called SNPs, are believed to have bio-geographic properties â€“ people endogenous to certain regions of the world … Click to read more!
How many founding Asian groups braved their way across the Bering land bridge during those frigid Pleistocene ice ages? Was it a single wave of people who later developed into the three distinct linguistic and cultural groups that populated the Americas, or were there multiple waves of people each with their own language and culture? Or was it some mix of the two? The issue has been and continues to be a topic of debate.
Linguistic studies of the Na-dene, Aleut-Eskimo, and Amerind language groups suggested that there were three waves across the land bridge, one for each language group. Recent genetic research, however, has suggested that there was only a single wave of founding groups into the Americas. (Read a free online review … Click to read more!
With the arrival of Black History Month and following on the heels of PBSâ€™s popular series â€˜African American Livesâ€™, increasing numbers of African Americans are deciding to explore the world of DNA testing and genetic genealogy. As a result many newspapers and magazines are taking the opportunity to introduce their readers to this increasingly popular avenue of genealogical research.
The Rocky Mountain News in Denver, Colorado is currently three articles into a six-part series examining the role and effect of genetic genealogy in African American research [Thanks to Genealogy Reviews Online]:

Genealogists interested in researching their Scottish roots will soon have a new resource thanks to a new genealogy center created by the
This testing will be done by mouth swab and will be conducted in a new forensics lab built at the University.Â The center will use both Y-chromosome and mtDNA results to build their database.Â Researchers at the University hope that the center will eventually be able to build a genetic map of the … Click to read more!
African Ancestry has had a very good year.Â The popular PBS series â€˜African American Livesâ€™, which analyzed the African roots of nine famous figures (such as Oprah, Quincy Jones, Whoopi Goldberg, Chris Tucker, and Dr. Sara Lawrence-Lightfoot), used the African Lineage Database developed by the Scientific Director of African Ancestry, Dr. Rick Kittles.Â This publicity has resulted in African Ancestry being featured in a wide array of newspaper and magazine articles around the world.
African Ancestry offers two types of DNA analysis, the Matriclan test and the Patriclan test.Â The Matriclan test sequences a portion of an individualâ€™s mtDNA to determine whether the ancestry of that lineage is African, European, or other ethnic … Click to read more!
Researchers have analyzed the (abstract here) HVR1 (hypervariable region 1) of the mtDNA control region belonging to an ancient female skeleton.Â The skeleton, approximately 3,600 years old, was discovered in 1980 in a frozen Neolithic grave in northeastern Siberia.
Sequencing of a 377-base pair fragment (16015-16391) revealed three mutations; C16223T, T16298C, and C16327T.Â These mutations are characteristic of haplogroup C in Siberian and Asian … Click to read more!
