The role of genetic variants in FCGR2A on the risk of rheumatoid arthritis in the Han Chinese population

Background: Rheumatoid arthritis (RA) is the most common inflammatory arthritis and is characterized by irreversible joint damage and deformities, which is largely caused by genetic factors. The aim of this study was to explore the role of FCGR2A polymorphisms with the susceptibility to RA in the Han Chinese cohort.Methods: We enrolled 506 RA patients and 509 healthy controls, with four single nucleotide polymorphisms (SNPs) successfully genotyped using Agena MassARRAY. Genetic models, haplotype analyses were applied to assess the association between FCGR2A polymorphisms and RA. And we evaluated the relative risk by odds ratios (ORs) and 95% confidence intervals (95% CIs) using logistic regression analysis.Results: The results revealed that FCGR2A rs6668534 was significantly related to an increased risk of RA in the overall (OR = 1.24, 95%CI = 1.04 – 1.48, p = 0.014). There was no any association found between the polymorphisms and RA risk at age > 54 years, while the two (rs6671847 and rs1801274) of the four SNPs possibly contributed to the susceptibility to RA at age ≤ 54 years. And the rs6668534 polymorphism conferred the increased susceptibility to RA in the male population. The haplotypes in the FCGR2A gene was significantly associated with the RA risk.Conclusions: Our research have demonstrated that the FCGR2A gene polymorphisms (rs6671847, rs1801274 and rs6668534) were implicated in RA susceptibility in the Han Chinese population.
