Polymorphisms of TNFAIP3 Gene in a Chinese Han Population with Fuchs Heterochromic Iridocyclitis

Purpose: This study was performed to evaluate the potential association of the tumor necrosis factor alpha inducible protein 3gene (TNFAIP3) polymorphisms with Fuchs' heterochromic iridocyclitis (Fuchs' Syndrome) in a Chinese Han population. Methods: Five single-nucleotide polymorphisms (SNPs), rs10499194, rs610604, rs7753873, rs5029928 and rs9494885 of TNFAIP3 were genotyped in 225 Fuchs' syndrome patients and 651 healthy controls using a PCR-restriction fragment length polymorphism assay. All control subjects were matched ethnically and geographically with the patients. Genotype counts in patients and controls were analyzed by the chi(2) test. Results: All genotypic and allelic frequencies of the tested TNFAIP3 polymorphisms were in Hardy-Weinberg equilibrium. The genotypic and allelic frequencies of rs10499194, rs610604, rs7753873, rs5029928 and rs9494885 of TNFAIP3 were not different between patients with Fuchs' syndrome and controls. Conclusions: Our results suggest that rs10499194, rs610604, rs7753873, rs5029928 and rs9494885 of TNFAIP3 are not associated with Fuchs' syndrome in a Chinese Han population
