Evaluation of the Association Between CD143 Gene Polymorphism and Psoriasis
Increased CD143 activity has been detected in various skin tissues, and this increase is partially caused by the intronic ID polymorphism. The genetic contribution of CD143 ID polymorphism to the progression of psoriasis, the commonest skin disease, has been extensively investigated, but reported with inconsistent results. The aim of this work was to gain new insights to shed light on the association between CD143 ID polymorphism and psoriasis risk. We systematically identified the studies examining the association of CD143 ID polymorphism with psoriasis risk. A meta-analysis combining data from all eligible studies was carried out. To evaluate the genetic association, we calculated odds ratio (OR) and its 95 % confidence intervals (CIs) for both genotypic models and allelic model. The final pooling dataset comprised ten studies. Meta-analysis of total samples did not suggest a notable association with psoriasis risk. However, subgroup analysis by ethnicity revealed a statistically significant association in East Asian samples (DD + ID vs. II: OR 0.86, 95 % CI 0.75–0.99, Pheterogeneity = 0.970; DD vs. ID: OR 0.85, 95 % CI 0.73–0.99, Pheterogeneity = 0.868; D vs. I: OR 0.86, 95 % CI 0.76–0.97, Pheterogeneity = 0.994). This meta-analysis demonstrated that the presence of CD143 ID polymorphism may modify the risk of psoriasis in individuals with East Asian ancestry.
