Genetic variation and discriminating power of four DNA microsatellites in the Russian population

The allele and genotype frequency distributions of four STRs (the LPL, vWA, FES/FPS, and F13B loci) commonly used in forensic medicine were studied with a sample of 200 ethnic Russians from Siberia. Genetic and molecular diversity of the four STRs was characterized in comparison with the American Caucasoid population. The set of the four STRs showed a high power of discrimination (PD = 0.99975). Comparison of the genetic variation at the four loci revealed a considerable difference between the Russian and American Caucasoid populations, precluding the use of data on allele frequencies in American Caucasoids for forensic testing in Russia. The results can be used as a reference in Siberia.
