HOUSTON, Oct. 12 -- Family Tree DNA, whose growing array of DNA tests for genealogical purposes has established them as the world leader in genetic genealogy, will introduce ground-breaking new X chromosome tests (X-STR) in early October. The X-STR tests are the first ever available for genealogy applications by focusing on linked "haplotype blocks" which are inherited intact over several generations. This test will be processed locally at the company's recently established Genomic Research Center. Headed by Thomas Krahn, whose German-based DNA-Fingerprint company was recently merged into Family Tree DNA, the state of the art Genomic Research Center is located at Family Tree DNA's Houston, Texas headquarters.
Krahn, a graduate of the Technical University of Berlin, is an expert in developing new molecular biological methods to resolve questions in biological heritage. Since 2003, DNA-Fingerprint specialized in more complex ancestry testing. This will give Family Tree DNA the ability to increase its current 67-marker Y-DNA test, the highest resolution Y-DNA test offered by any company in the world today, to over 100 Y-DNA markers.
Additionally, the new lab has allowed Family Tree DNA to significantly lower the price of its Full Mitochondria Genomic Sequence (FGS), which it began to make available a year ago. The Full Mitochondria Genomic Sequence is the last mtDNA test that anyone will ever need to take because it encompasses the entire molecule (all 16,659 base pairs) and is clearly the emerging platform for all Anthropology testing. The new lab also affords the capability to offer testing for CODIS markers for those who want to compare test results against existing databases of these universally used markers, including biographical databases.
