Analysis of genetic diversity of Russian regional populations based on STR markers used in DNA identification

Analysis of genetic diversity of Russian regional populations based on STR markers used in DNA... We conducted the first genetic analysis of a wide a range of rural Russian populations in European Russia with a panel of DNA markers commonly used in Human DNA identification. We examined a total of 647 samples from indigenous ethnic Russian populations in Arkhangelsk, Belgorod, Voronezh, Kursk, Rostov, Ryazan, and Orel regions. We employed a multiplex genotyping kit, COrDIS Plus, to genotype Short Tandem Repeat (STR) loci, which included markers officially recommended for DNA identification in the Russian Federation, the United States, and the European Union. In the course of our study, we created a database of allele frequencies, examined the distribution of alleles and genotypes in seven rural Russian populations, and analyzed the genetic relationships between these populations. We found that, although multidimensional analysis indicated a difference between the Northern Russian gene pool and the rest of the Russian European populations, a pairwise comparison using 19 STR markers among all populations did not reveal significant differences. This is in concordance with previous studies, which examined up to 12 STR markers in urban Russian populations. Therefore, the database of allele frequencies created in this study can be applied for forensic examinations and DNA identification among the ethnic Russian population over European Russia. We also noted a decrease in the levels of heterozygosity in the northern Russian population compared to southern and central Russian populations, which is consistent with trends identified previously using classical gene markers and analysis of mitochondrial DNA. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

We conducted the first genetic analysis of a wide a range of rural Russian populations in European Russia with a panel of DNA markers commonly used in Human DNA identification. We examined a total of 647 samples from indigenous ethnic Russian populations in Arkhangelsk, Belgorod, Voronezh, Kursk, Rostov, Ryazan, and Orel regions. We employed a multiplex genotyping kit, COrDIS Plus, to genotype Short Tandem Repeat (STR) loci, which included markers officially recommended for DNA identification in the Russian Federation, the United States, and the European Union. In the course of our study, we created a database of allele frequencies, examined the distribution of alleles and genotypes in seven rural Russian populations, and analyzed the genetic relationships between these populations. We found that, although multidimensional analysis indicated a difference between the Northern Russian gene pool and the rest of the Russian European populations, a pairwise comparison using 19 STR markers among all populations did not reveal significant differences. This is in concordance with previous studies, which examined up to 12 STR markers in urban Russian populations. Therefore, the database of allele frequencies created in this study can be applied for forensic examinations and DNA identification among the ethnic Russian population over European Russia. We also noted a decrease in the levels of heterozygosity in the northern Russian population compared to southern and central Russian populations, which is consistent with trends identified previously using classical gene markers and analysis of mitochondrial DNA.
