title: [Polymorphism of DNA repair genes (XRCC1, XRCC3, XPC, XPD, XPA) in ethnic groups from Republic of Bashkortostan].
abstract: Genotype and allele-frequency distributions of the excision and homologous recombination of DNA repair genes XRCC1 (rs25487 and rs25489), XRCC3 (rs861539), XPC (rs2228001), XPD (rs13181), XPA (rs1800975) were examined in three ethnic groups from the Republic of Bashkortostan (Russia), Russians, Tatars, and Bashkirs. The data obtained were compared to those for other ethnic groups from Russia and worldwide. Statistically significant differences in the allele-frequency distribution of the XPA gene polymorphic locus rs1800975 (p = 0.03) between the samples of Russians and Tatars were demonstrated. Russians and Bashkirs differed in the allele-frequency distribution of the rs861539 polymorphic locus of the XRCC3 gene (p < < 0.0001), and Tatars and Bashkirs, at the rs861539 locus of the XRCC3 gene (p < 0.0001). In Russians and Tatars from the Republic of Bashkortostan, allele frequencies at the DNA repair gene polymorphic loci examined were consistent with those in the population of Northern and Western Europe, while polymorphic allele-frequency distributions in Bashkirs was similar to that observed in the ethnic group of Gujarati Indians.
