Like the association between FCGR2A and clinical response of IFX, they found a nominally significant association between RGS12 SNP rs2857859 and response to IFX in anti-CCP positive RA patients (OR = 0.4; CI95% = 0.17–0.99; uncorrected p = 0.042). The gene discussed is RGS12; the disease is rheumatoid arthritis.
