title: [Distribution of alleles of DRB, DQB and DQA loci of major histocompatibility complex in healthy donors of Saint Peterburg].
abstract: The distribution of alleles of DRB, DQB and DQA loci was investigated in 118 healthy donors from St. Petersburg. Said alleles were identified by the restriction fragment length polymorphism method using DRB, DQB and DQA probes after TaqI digestion and Southern blotting. The frequencies of said alleles were compared with those of a cohort of healthy donors living in Germany. A significantly higher frequency of DRB-17-2 was identified in the Russian donors, as compared with the German counterparts. Also, the Russian donors revealed a decrease in the frequency of DQB-1 (P = 0.01) and an increase in that of DQB-X allele (P = 0.05). An analysis of DRB, DQB and DQA locus a alleles adhesion in a sample of donors from St. Petersburg showed it to agree, in a large proportion of cases, with the literature data. A parallel study of immunological specificity of DR antigen was undertaken to compare the results of genetic and serologic typing; errors in DR specificity identification were found to have been made in 17.0%.
