    Abstract:
    The aim of this study was to examine the role of single nucleotide polymorphisms (SNPs) and haplotypes of the tumor necrosis factor ligand superfamily member 15 (TNFSF15) gene in Hungarians with psoriasis and psoriatic arthritis. A case-control study was performed, and five TNFSF15 SNPs (rs3810936, rs6478108, rs6478109, rs7848647, rs7869487) were genotyped in 319 patients with psoriasis, 105 of whom also have psoriatic arthritis, and in 200 healthy individuals. Three haplotypes (A, B, C) based on these five SNPs were also analyzed. Our findings suggest that the rs6478109 SNP may be a genetic risk factor in psoriasis (p=0.0046), while haplotype C may be protective (p=0.0250). These results suggest that certain variants of the TNFSF15 gene contribute to the pathogenesis of the immune-mediated, multifactorial skin disease psoriasis, and that this difference is more readily apparent when groups of patients with and without psoriatic arthritis are examined separately.
