Glutathione-S-transferase gene polymorphism in Russian populations of European part of Russia

Glutathione-S-transferase gene polymorphism in Russian populations of European part of Russia Distribution of several widespread, extensively studied polymorphic variants of genes of the cytosol glutathione-S-transferase subfamily (GSTA1, GSTM1, GSTM3, GSTP1, and GSTT1) has been studied in samples from Russian populations of European Russia, as well as Komi and Yakut populations used for comparison. Analysis of the GSTP1 and GSTM3 polymorphisms has not revealed significant differences in the distribution of alleles of the loci, including two-site GSTP1 haplotypes, in most Russian populations and between Komi populations. Only in the Yakut sample have a significant difference been found with respect to these loci in each pairwise comparison. Regarding the GSTT1 and GSTA1 genes, in addition to differences between the Yakut population and all other populations with respect to the GSTA1 gene, it has been found that the frequencies of the GSTT1 0/0 deletion genotype and GSTA1 −69T allele in the Russian sample from Mezen’ (Arkhangel’sk oblast) are substantially lower than in other Russian populations and Komi populations. The significance of these differences has been confirmed by tests for heterogeneity of the entire pool of Russian populations. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

Distribution of several widespread, extensively studied polymorphic variants of genes of the cytosol glutathione-S-transferase subfamily (GSTA1, GSTM1, GSTM3, GSTP1, and GSTT1) has been studied in samples from Russian populations of European Russia, as well as Komi and Yakut populations used for comparison. Analysis of the GSTP1 and GSTM3 polymorphisms has not revealed significant differences in the distribution of alleles of the loci, including two-site GSTP1 haplotypes, in most Russian populations and between Komi populations. Only in the Yakut sample have a significant difference been found with respect to these loci in each pairwise comparison. Regarding the GSTT1 and GSTA1 genes, in addition to differences between the Yakut population and all other populations with respect to the GSTA1 gene, it has been found that the frequencies of the GSTT1 0/0 deletion genotype and GSTA1 −69T allele in the Russian sample from Mezen’ (Arkhangel’sk oblast) are substantially lower than in other Russian populations and Komi populations. The significance of these differences has been confirmed by tests for heterogeneity of the entire pool of Russian populations.
