    Abstract:
    Polymorphism of tumor necrosis factor alpha-induced protein 3 (TNFAIP3) has been be related to various auto-immune diseases. Based on previous studies that the single nucleotide polymorphism (SNP) of rs2230926 was association with rheumatoid arthritis (RA) of Japanese, Caucasian population and the northern Chinese Han population, we tested the alleles and geno-type frequencies of rs2230926 in TNFAIP3 to investigate whether rs2230926 is susceptible to RA of southern Chinese Han population. In our case-control association study, 207 RA patients fulfilling the American College of Rheumatology (ACR) 1987 criteria were compared with 199 unrelated healthy subjects. After testing the alleles and genotype frequencies of rs2230926, the airwise linkage disequilibrium (LD) was computed and odd ration (OR) and 95% confidence intervals (95% CI) were used for evaluating the susceptibility to RA. The SNP of rs2230926 of the cases and control subjects were conformed to the Hardy-Weinberg equilibrium (P = 0.02257). The significantly statistical differences in alleles of T, G were founded in the cases and controls (P = 0.0027, OR 0.417, 95% CI 0.232-0.749); the genetic types of rs2230926 were associated with a susceptibility to RA, with OR 0.375 (95% CI 0.198-0.707, P = 0.0018). In the present study, our results indicated that the genetic polymorphism of rs2230926 in TNFAIP3 may be a susceptible factor conferring risk for RA in southern Chinese Han population.
