| Summary: | Psoriasis vulgaris is chronic skin disease that is linked to genetics and immune system. The most important predisposing genetic factor is human leukocyte antigen (HLA). This study was performed to determine the relationship between HLA-Cw6 allele and psoriasis vulgaris and the changes of nucleotide base squences, using observation method with a cross sectional comparative study. Samples were selected using consecutive sampling of 30 patients with psoriasis vulgaris attending the Dermatology and STD polyclinic at DR. M. Djamil Hospital. 30 healthy volunteers were selected as controls. The subjects’ medical history was recorded followed by a dermatological examination, collection of samples, DNA isolation, then primers were designed for HLA-Cw6 allele, genes were sequencing and finally analyzed using PCR-SSP. The results were 20% of patients with psoriasis vulgaris carried HLA-Cw6 allele, while it was absent in the control group. This difference is statistically significant at the 5% level (p = 0.024). We found the changes of nucleotide base formations of HLA-Cw6. In conclusion, based on these observations, presence of the HLA-Cw6 allele is an important genetic risk factor for developing psoriasis vulgaris.
