Allelic polymorphism of F2, F5 and MTHFR genes in population of Ukraine.

Analysis of F2, F5 and MTHFR genes SNPs allelic variants in population of Ukraine. Polymorphic variants were analyzed in 172 unrelated individuals using PCR followed by RFLP analysis. Following genotypes have been identified: GG (97%), GA (3%) for F2 gene G20210A SNP, GG (96.5%), GA (3.5%) for F5 gene G1691A SNP and CC (49.5%), CT (43%), TT (7.5%) for MTHFR gene C677T SNP. Following combined genotypes have been detected. We observed 1.7% heterozygous carriers of MTHFR gene 677T SNP which were heterozygous for one of the alleles of F5 1691A or F2 20210A genes. On the other hand, the 7.5% MTHFR gene 677T SNP homozygous individuals carried wild type alleles only of F5 and F2 genes. None of the individuals was carrying F5 1691A and F2 20210A genes polymorphic variants simultaneously. The data about F2, F5 and MTHFR genes SNPs allelic frequencies in the population of Ukraine have been obtained. Thus, distribution of F2, F5 and MTHFR genotypes based on analysis of SNP in those three genes simultaneously has been detected.
