Open Access Abstract Introduction A feature of rheumatoid arthritis RA is an imbalance between proinflammatory and anti-inflammatory cytokines. Several recent studies have implicated polymorphism in the IL-4 signalling pathway in the development of erosive RA. The aim of the present study was to investigate the role of polymorphism in the IL-4 IL-4Ra and IL-13 genes in RA including an examination of epistasis. Methods A total of 965 Caucasian patients with RA cases and 988 healthy control individuals controls were genotyped for five variants in the IL-4 IL-13 gene cluster and two functional variants IL-4Ra . Individual genotype and haplotype frequencies were compared between cases and controls. The odd ratios were calculated with asymptotic 95 confidence intervals and P values less than were considered statistically significant. The potential association with radiological joint damage was also examined. Potential gene .
