Statistically significant associations were also found between rheumatoid arthritis and FCGR3A F158V polymorphisms (recessive: OR = 1.36, 95% CI 1.09-1.69, for VV vs. FF + FV, and allele comparison: OR = 1.15, 95% CI 1.03-1.29, for V vs. F, in the overall analyses). This evidence concerns the gene FCGR3A and rheumatoid arthritis.
