Genetic association of aromatic hydrocarbon receptor and its repressor gene polymorphisms with risk of rheumatoid arthritis in Han Chinese populations.

ABSTRACT: The goal of this study was to evaluate the potential relationship among polymorphisms of aromatic hydrocarbon receptor, aromatic hydrocarbon receptor repressor, and rheumatoid arthritis (RA) susceptibility as well as the association among the polymorphisms of aromatic hydrocarbon receptor, aromatic hydrocarbon receptor repressor, and their expression.We performed a hospital-based, case-control study of 400 patients with RA and 726 healthy controls in Han Chinese populations. Two single-nucleotide polymorphisms were selected for genotyping including aromatic hydrocarbon receptor (rs2066853) and aromatic hydrocarbon receptor repressor (rs2292596).To single-nucleotide polymorphism rs2292596, a statistically significantly increased risk of RA was found to be associated with the G allele of rs2292596; the odds ratio was 2.170 (95% confidence interval: 1.820-2.587). Unfortunately, no significant differences exhibited in the allelic and the genotype frequencies of rs2066853 between 2 groups. We failed to find any association between rs2066853, rs2292596 genotypes and their expression of patients, respectively. No statistical relationship was found between aromatic hydrocarbon receptor, aromatic hydrocarbon receptor repressor at messenger Ribonucleic acid levels and clinical data, either.This study demonstrated that the polymorphisms of rs2292596 was significant with genetic susceptibility to RA patients; furthermore, it suggests the G allele of rs2292596 might be associated with a dangerous effect on RA in Han Chinese populations.

Project description:BackgroundRheumatoid arthritis (RA) is a systemic autoimmune disease characterized by chronic destructive inflammation in synovial joints. It is well known that genetic and environmental risk factors and their interaction contribute to RA pathogenesis. This study aimed to investigate the association between the critical polymorphisms in the tumor necrosis factor α (TNFα)-induced protein 3(TNFAIP3) gene and the risk of RA in a large northern Chinese Han population.MethodsA case-control study of 1280 RA patients and 1280 matched healthy controls was conducted.ResultsThis study showed that carriers of the rs2230926 TG genotype or rs10499194 CT genotype had an increased risk for RA compared with those carrying the wild genotype (rs2230926: OR = 1.48, 95% CI = 1.17-1.86, p = 0.001; rs10499194: OR = 2.00, 95% CI = 1.46-2.74, p < 0.001). The combined rs2230926TG/GG or rs10499194 CT/TT were associated with an increased risk of RA (ORs were 1.50 and 2.01, 95% CIs were 1.19-1.88 and 1.47-2.74, respectively, both p < 0.001). There was not significant association between rs13207033 polymorphism and RA risk. Subset analysis stratified to gender showed that the increased risks were significant among the genotypes TG, TG/GG of rs2230926 and CT, CT/TT of rs10499194 and the corresponding ORs were 1.42 (95% CI = 1.10-1.83, p = 0.006), 1.44(95% CI = 1.12-1.85, p = 0.004), 1.52(95% CI = 1.05-2.20, p = 0.026) and 1.52(95% CI = 1.06-2.19, p = 0.023) in the female population. Stratified analyses by age found that rs2230926(TG, TG/GG) and rs10499194(CT, CT/TT) polymorphisms were associated with RA risks in population ≤53 years old and among >53 years old only rs10499194(CT, TT, CT/TT) polymorphism had significant results. The interaction analysis suggested that individuals with both risk genotypes of the two SNPs have a higher elevated risk of RA than those with only one of them (ORs were 3.44 compared to 1.74 and 1.35). The haplotype results showed that individuals with the rs2230926G-rs13207033G-rs10499194C haplotype were associated with increased risks of RA (OR = 1.37, 95% CI = 1.08-1.74, p = 0.010).ConclusionsRs10499194 and rs2230926 polymorphisms in the TNFAIP3 gene region may be susceptibility factors for rheumatoid arthritis in the northern Chinese Han population.
