Rheumatoid arthritis (RA) is a systemic, chronic, and inflammatory autoimmune disease with a strong genetic component. gene variant rs255758 has been reported as a candidate for RA susceptibility. A replication study was performed on this variant by taking 188 RA cases and 310 healthy non-RA controls from northwest India in a case-control association study design.
DNA isolated from collected blood samples was analyzed by genotyping of the variant on real-time polymerase chain reaction using TaqMan Allele Discrimination Assay and statistically analyzed.
The variant was found to follow Hardy-Weinberg Equilibrium ( = 0.079) in the control group. The variant was significantly associated with RA susceptibility in the present studied population cohort ( = 0.024) with as a risk allele and increased risk in the recessive model ( vs. + ; = 0.004).
The present study corroborates the earlier findings on the role of gene variant rs255758 in RA and further contributes to its genetic etiology.
类风湿性关节炎（RA）是一种具有强烈遗传成分的全身性、慢性炎症性自身免疫疾病。基因变体rs255758已被报道为RA易感性的候选基因。在一项病例对照关联研究设计中，从印度西北部选取了188例RA病例和310名健康非RA对照，对该变体进行了复制研究。
使用TaqMan等位基因鉴别分析通过实时聚合酶链反应对从采集的血样中分离的DNA进行该变体的基因分型分析，并进行统计学分析。
在对照组中发现该变体符合哈迪-温伯格平衡（P = 0.079）。在本研究的人群队列中，该变体与RA易感性显著相关（P = 0.024），其中作为风险等位基因，在隐性模型中风险增加（与+；P = 0.004）。
本研究证实了先前关于基因变体rs255758在RA中的作用的发现，并进一步为其遗传病因学做出了贡献。
