The genotype distribution of IL10-1082A/G and TGFB1-509C/T polymorphisms was in agreement with HWE among RA cases (chi-squared = 0.841, p = 0.841; chi-squared = 0.44, p = 0.878, respectively) and controls (chi-squared = 3.33, p = 0.1; chi-squared = 0.451; p = 0.33, respectively). The gene discussed is TGFB1; the disease is rheumatoid arthritis.
