    Abstract:
    We have studied the distribution of HLA DRB1, DQA1, DQB1 alleles and haplotypes in a sample of 103 unrelated healthy individuals from the region of Lodz in central Poland by the polymerase chain reaction and hybridization with allele-specific oligonucleotide probes (PCR-SSO). DRB1*0101, DRB1*07, DRB1*1501, DRB1*03 and DRB1*11 were the most frequent alleles at the DRB1 locus. The DRB1*04 group was observed at a high frequency, but only five out of the 19 DR4 subtypes tested were observed. The most frequent was DRB1*0401, followed by DRB1*0403, DRB1*0402, DRB1*0407 and DRB1*0417. Eight DQA1 alleles were found in this Polish population, among which DQA1*0501, DQA1*0101 and DQA1*0102 were the most frequent. At the DQB1 locus 13 alleles were found. Among them, four were present with frequencies above 10%: DQB1*0201, DQB1*0301, DQB1*0501 and DQB1*0602. Our results underline significant differences between the population of central Poland and populations of neighbouring countries such as Germany, Ukraine and the Czech Republic. This study will serve as a reference for further anthropological studies, as well as studies of associations between HLA and disease.
