Association of miRNA-146a Gene Polymorphism Rs2910164 with Behcet's Disease: A Meta-analysis.

Background A meta-analysis was performed by summarizing relevant researches to evaluate the relationship between miRNA-146a gene polymorphism rs2910164 and Behcet's disease (BD). Methods A systematic search of published studies was conducted in PubMed and Embase. Five eligible studies involving 1167 BD cases and 1662 controls were included in the current meta-analysis. Results The results suggested that the polymorphism rs2910164 was correlated with BD susceptibility in all genetic models. In subgroup analysis according to ethnicity, the relationship between this polymorphism and BD was more significant in Caucasians (allele model: OR = 0.49, 95% CI 0.39-0.61; heterozygote model: OR = 0.35, 95% CI 0.26-0.47; homozygote model: OR = 0.29, 95% CI 0.16-0.53; dominant model: OR = 0.34, 95% CI 0.25-0.45; recessive model: OR = 0.56, 95% CI 0.50-0.72) than that in Asians. Conclusion In conclusion, this meta-analysis indicates that miRNA-146a gene polymorphism rs2910164 G allele confers BD susceptibility, especially in Caucasians.
