Title : Influence of FCGR3A-V212F and TNFRSF1B-M196R genotypes in patients with rheumatoid arthritis treated with infliximab therapy.

Abstract : OBJECTIVE: Anti-TNF-alpha therapies are widely used in rheumatoid arthritis (RA) patients. Despite their clearly proven efficacy, some discrepancies were observed in the treatment response with 40% of non-responder patients. The aim of this study is to determine whether two functional single-nucleotide polymorphisms, V212F in the FCGR3A, and M196R in the TNFRSF1B genes correlate with rheumatoid arthritis susceptibility and response to anti-TNF-alpha therapy. METHODS: The population study was composed of a French cohort of 78 RA patients and 70 healthy controls. Allele and genotype frequencies were compared between patients and controls, according to their response to infliximab therapy, using the American College of Rheumatology (ACR) response criteria. RESULTS: No association was found between these two SNPs and RA susceptibility. A significant correlation was found between 196R allele carriers and low response to infliximab therapy. CONCLUSION: This is the first report of a statistically significant association between the TNFRSF1B-M196R SNP and response to infliximab in a French cohort. Larger studies are needed to confirm the relevance of this association.
