DNA Tribes is a personal genomics and biotechnology company based in Arlington, Virginia, USA, that allows individuals to have their genetic ancestry analyzed based on autosomal STR genetic markers developed by the FBI for individual identification in a forensic context. Autosomal DNA is inherited from both maternal and paternal ancestors. The methodology is a cheek swab kit which is delivered to the customer's home and then sealed and returned for analysis. Results are delivered to the customer via e-mail. The analysis identifies a person's best genetic fits among actual world populations.
Autosomal STR tests
The DNA Tribes tests look at autosomal short tandem repeat STR genetic markers. Autosomal STRs were developed by the FBI for individual identification. Using this system, each person's DNA profile serves as a genetic fingerprint for that individual, with typically less than one in a trillion chance of sharing an identical profile with anyone in the world. Because each autosomal STR profile is so unique to each person, these genetic markers are also the industry standard for court-admissible paternity and maternity testing. DNA Tribes use this highly unique autosomal STR genetic profile to measure a person’s genetic connections to populations and major regions around the world. These are the same genetic markers developed and used by the National Institute of Standards and Technology in the United States.
DNA Tribes' proprietary analysis has been developed by Dr. Eduardas Valaitis, whose background includes extensive work in multivariate analysis and classification, which involves identifying mathematical structure present within large and complex datasets. The company performs an analysis of world populations to identify genetic structure.
As of July 2013 DNA Tribes offer tests at two different levels: 22 and 26 markers. Previously tests were offered at three different levels: 15, 21 and 27 markers.
Currently, DNA Tribes has 920 sample populations in its autosomal STR database collected by researchers from 305,000 individuals, including 673 populations classified as indigenous populations, and 195 populations classified as Diaspora populations, including multiple Jewish populations from Israel and the world Jewish Diaspora.
DNA Tribes' world region analysis is based on the subdivision of ten inhabited major world regions including: European, Near Eastern, Native North American, Sub-Saharan African, Central Asian, South Asian, East Asian, Native Central American, Native South American, and Pacific. These regions are divided into 36 world sub-regions.
Autosomal SNP analysis
DNA Tribes do not sell any autosomal SNP tests but they do offer an autosomal SNP analysis service. A geographical "deep ancestry" analysis can be performed using the raw data from any one of the companies that offers a SNP microarray test. The reports provide admixture percentages, multi-dimensional scaling (MDA) plots and a genotype comparison with over 280 populations in the company's SNP database.
