HLA gene and haplotype frequencies in the population of southern Poland.

Results of a population study on frequencies of phenotypes and genotypes of the HLA system (locus A and B) in 240 adults, unrelated and of both sexes, living in southern Poland are reported. Frequencies of haplotypes were calculated according to Mattiuz et al. Distribution of all HLA specificities conformed with the Hardy-Weinberg law and was similar to the distribution in other white populations, except HLA-B13 which had a phenotype frequency of 14.17% and gene frequency 7%. Haplotype frequencies and positive and negative association were analogous with those in other white populations.
