[Assessment of the frequency of finding polymorphic alleles of the human X-chromosome locus DXS52 in the Muscovite population].

The frequency of different polymorphic variants of the multiallelic locus DXS52 (St14) of the human X-chromosome, adjacent to the factor VIII gene, was evaluated by means of PCR for the heterogeneous population of Moscow and Moscow oblast'. It was shown that the heterozygosity index of this polymorphism in the studied population is much lower (0.71) than in Western Europe (0.
