In this same study an association was found in 55 Caucasian patients (from Spain) diagnosed with RA and being treated with RTX between the FCGR3A rs396991-C allele and LDA after 18 months of treatment with RTX (C vs. AA; p = 0.077; OR = 4.90; 95% CI = 0.84-28.48) [9]. Here, FCGR3A is linked to rheumatoid arthritis.
