Polymerase chain reaction (PCR)‐based genotyping was used to characterize the features of HLA class II molecular polymorphisms in a Slavic population of North‐Western Russia. Two hundred individuals were analyzed for the DRB1 gene, and 100 persons randomly selected from this cohort were additionally typed for DQA1, DQB1 and DPB1 genes. Allele and haplotype frequencies were found to be similar to those observed in other Caucasian populations, with the exception of considerably high prevalence of the DPB1*0301 allele (16.0%) in the group studied. The high rate of diversity was observed within DRB1*04 and DRB1*14 specificities, as well as for extended DR‐DQ haplotypes. In addition, significant number of “unusual” DR‐DQ linkage patterns have been detected. The data seem to reflect the complexity of ethnic background of “European” Russians and may be helpful for the development of international network between donor registries.
