Prevalence of the HLA-Cw6 genotype and zinc deficiency in psoriasis vulgaris patients in Indonesia.

Introduction: Psoriasis vulgaris is an immune-mediated inflammatory disease influenced by genetic and immunologic factors, including micronutrient deficiencies. The HLA-Cw6 gene and zinc level have been separately studied in psoriasis patients, yielding inconsistent findings. A descriptive study regarding HLA-Cw6 allele expression, zinc levels, and their direct correlation in Indonesia is lacking.
