The association between genetic polymorphisms of interleukin 23 receptor gene and the risk of rheumatoid arthritis: An updated meta-analysis.

This meta-analysis was conducted to confirm whether seven single nucleotide polymorphisms (SNPs) of interleukin-23 receptor (IL23R) gene are associated with rheumatoid arthritis (RA) susceptibility. RevMan version 5.3 was used to calculate statistical data. Sixteen articles involving 11,816 RA patients and 14,268 healthy controls were included in this meta-analysis. A significant association was identified between the rs11209026 polymorphism and RA susceptibility in Caucasians (AA vs. GG: OR = 1.78, 95% CI = 1.02-3.10, P = .04; AA vs. AG + GG: OR = 1.77, 95% CI = 1.02-3.08, P = .04). Additionally, our result showed that the G allele of IL23R/rs10489629 had a significantly increased frequency in RA patients of Caucasians and Asians (A vs. G: OR = 0.92, 95% CI = 0.88-0.97, P = .002; OR = 0.62, 95% CI = 0.44-0.87, P = .006, respectively). Furthermore, the meta-analysis revealed a significant association between the rs1343151 polymorphism and RA susceptibility in Caucasians (C vs. T: OR = 0.91, 95% CI = 0.87-0.96, P = .0004). Our meta-analysis confirmed the IL23R gene might be treated as a susceptible factor for RA.
