The ERAP1 (rs26653) polymorphism was found to increase the disease risk in patients with AS and IBD compared with the control group (p=0.02 and p=0.01, respectively).
Overall, six SNPs were associated with AS; two SNPs (rs27044 and rs26653) were not when all studies were pooled into the meta-analysis (rs27044 G vs. C, OR = 1.058, 95% CI = 0.827-1.354; rs26653 C vs. G, OR = 1.154, 95% CI = 0.937-1.422).
Meanwhile, its CC genotype and C allele were positively associated with the early onset of PsV (P = .036, OR = 2.080, 95% CI = 1.044-4.145; P = .034, OR = 1.443, 95% CI = 1.028-2.024) and increased PsV risk in the subgroup with family history (P = .029, OR = 2.149, 95% CI = 1.075-4.296; P = .027, OR = 1.466, 95% CI = 1.044-2.059).ERAP1 gene rs26653 polymorphism may increase the risk of PsV in Chinese Han population.
The aim of this case-control study was to elucidate the role of some single nucleotide polymorphisms (SNPs) in the ERAP1 (rs27524, rs27044, rs30187, rs2287987 and rs26653) and ERAP2 (rs2248374) genes in predicting the risk for psoriasis vulgaris in the Polish population.
ERAP1 single-nucleotide polymorphism rs26653, which, to our knowledge, has not previously been reported in psoriasis, is nonsynonymous, has suggestive functional consequences, and herein displays strong association with disease.
The ERAP1 (rs26653) polymorphism was found to increase the disease risk in patients with AS and IBD compared with the control group (p=0.02 and p=0.01, respectively).
