Objective:
This meta-analysis was conducted to investigate the relationship between the interleukin (IL)-17A rs2275913 polymorphism and rheumatoid arthritis (RA) susceptibility.
Methods:
Eligible studies were retrieved from PubMed, Embase, and Web of Science. The fixed- or random-effects model was used to calculate the pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) on the basis of heterogeneity.
Results:
Overall, 11 studies containing 4019 RA patients and 4137 controls were included in this meta-analysis. The results suggested a significant association between the IL-17A rs2275913 polymorphism and RA susceptibility in the overall population (allelic model A vs. G: OR = 0.89, 95%CI: 0.83-0.95; heterozygote model GA vs. GG: OR = 0.87, 95%CI: 0.78-0.96; homozygote model AA vs. GG: OR = 0.82, 95%CI: 0.71-0.96; dominant model GA + AA vs. GG: OR = 0.86, 95%CI: 0.78-0.94). In the subgroup analyses, the IL-17A rs2275913 polymorphism was significantly associated with RA risk in Europeans (allelic model A vs. G: OR = 0.87, 95%CI: 0.78-0.97; heterozygote model GA vs. GG: OR = 0.79, 95%CI: 0.68-0.93; dominant model GA + AA vs. GG: OR = 0.79, 95%CI: 0.68-0.92), but not in Africans or Americans.
Conclusion:
This study suggests that the IL-17A rs2275913 polymorphism is significantly associated with RA susceptibility in Europeans.INPLASY registration number: INPLASY202170056.
