The HLA (human leukocyte antigen) Cw*06 allele demonstrates the strongest association with susceptibility to early-onset psoriasis in most populations. Recent data have indicated that late-onset psoriasis (LOP) demonstrates only a weak association with Cw*0602, and suggest that this type of psoriasis may represent a distinct subtype of the disease. The aim of this study was to compare the frequency of human leukocyte antigen C (HLA-C) alleles in patients with LOP and in healthy subjects within the same ethnic group in northern Poland. HLA-C alleles of 89 patients with psoriasis with onset at the age of 40 y or later and 80 control subjects were determined by a polymerase chain reaction (PCR), low-resolution method. The results showed that the Cw*05 allele was detected less frequently in patients with LOP than in control subjects, but this failed to retain significance after correction for multiple comparisons. There were no differences in the frequency of other HLA-C alleles between the patients and the control group. Our results confirm no association between HLA-C alleles and LOP in the northern Polish population. The lack of this association supports the hypothesis about different genetic backgrounds of early- and late-onset psoriasis.
