Association of HLA class I antigens and HLA class II alleles with vitiligo in a Turkish population.
As is the case with many other autoimmune diseases, there is an association between vitiligo and HLA complex. HLA subtypes vary with racial/ethnic background. The purpose of this study was to determine which HLA class I antigens and HLA class II alleles are associated with Turkish vitiligo patients. Forty-one patients with vitiligo and 61 healthy control subjects were typed for HLA class II alleles. Thirty-three out of 41 patients with vitiligo and 100 healthy transplant donors were typed for HLA class I antigens. HLA DNA typing was performed by polymerase chain reaction/sequence specific primer method for class II. HLA typing for class I was performed by serological method. The frequency of HLA DRB1*03 was 0.6340 in patients compared to 0.2950 in controls (P = 0.0014). The frequency of HLA DRB1*04 was found to be 0.6830 in patients compared to 0.2950 in controls (P = 0.00026). The allele HLA DRB1*07 was present in 0.390 of patients compared to 0.0820 of the controls (P = 0.0004). A preventive antigen for the manifestation of vitiligo has not been identified in this study. Our findings suggest that DRB1*03, DRB1*04 and DRB1*07 alleles are genetic markers for general susceptibility to vitiligo in a Turkish population.
