Objective The aim of this study was to explore whether the miR-146a polymorphism (rs2910164) confers susceptibility to systemic lupus erythematous (SLE) and rheumatoid arthritis (RA). Methods A meta-analysis was conducted on the association of the miR-146a polymorphism with SLE and RA. Results Five studies with 2013聽patients and 2555聽controls were included in the meta-analysis. Meta-analysis revealed no association between SLE and the miR-146a聽G allele (odds ratio, OR聽=鈥?.007, 95鈥? confidence interval, CI聽=鈥?.910鈥?.114, p鈥?鈥?.888). Additionally, no associations were found between the miR-146a polymorphism and SLE using recessive or dominant models, or homozygote contrast. Meta-analysis using allele contrast, recessive and dominant models, as well as homozygote contrast failed to reveal an association between the miR-146a polymorphism and RA (OR for G聽allele聽=鈥?.114, 95鈥?聽CI聽=鈥?.892鈥?.391, p鈥?鈥?.342). Conclusion This meta-analysis demonstrates that the miR-146a polymorphism is not associated with susceptibility to SLE and RA. However, considering the small number of studies, further studies are needed to confirm this result.
