摘  要:目的:探讨骨保护素(OPG)基因163A/G及245T/G单核苷酸多态性(SNPs)与我国汉族人群类风湿关节炎( RA)发病的相关性。方法:采用聚合酶链反应-限制性片段长度多态性( PCR-RFLP)技术检测我国南方汉族正常人群及RA患者的OPG 163A/G和245T/G 2个SNP位点;进行Hardy-Weinberg平衡检验;计算基因型和等位基因频率,及这2个位点的连锁关系,并分析这2个SNP位点与RA的关系。结果:所研究基因分布符合Har-dy-Weinberg平衡,163A/G位点基因型AA、AG、GG分布频率在2组比较有显著差异( P<0.05);等位基因A、G分布比较在2组有显著差异(P<0.05),携带163GG基因型者发生RA的危险性是非携带者的1.219倍(OR=1.219,95%CI:1.066~2.339, P<0.05)。但245T/G位点各基因型及等位基因频率在2组中均未见差异(P>0.05)。结论:OPG基因163A/G SNP可能与我国汉族人群RA发病相关,携带G等位基因可能是发病的危险因素。AIM: To investigate the association of osteoprotegerin ( OPG) gene single nucleotide polymor-phisms (SNPs), 163A/G (rs3102735) and 245T/G (rs3134069), with susceptibility to rheumatoid arthritis (RA) in Chinese Han population .METHODS:A total of 205 patients with RA and 171 healthy control subjects were enrolled into this study.Genotyping was performed by polymerase chain reaction-based restriction fragment length polymorphism and subsequently confirmed by DNA sequencing .Odds ratio ( OR) and 95%confidence intervals ( CI) were calculated for the risk genotypes and alleles .RESULTS: OPG gene polymorphisms 163A/G and 245T/G were conformed to the Hardy-Weinberg equilibrium .The statistical differences in the genotypes of AA , AG and GG at 163A/G locus were found in RA and controls.The G allele was associated with an increased risk of RA , with OR of 1.219 (95%CI:1.066~2.339).No significant difference was observed between RA group and control group with respect to genotypic and allelic frequencies of OPG gene 245T/G (P>0.05).CONCLUSION:The OPG gene 163A/G SNP may be associated with RA susceptibility , and G allele may be the risk factor for developing RA .
