先前的证据表明,PRL-1149 T(次要)等位基因降低催乳素表达,可能与自身免疫性疾病有关。我们的目标是确定PRL-1149 G/T多态性(rs 1341239)在类风湿关节炎(RA)易感性中的作用。我们在四个独立的样本中检测了PRL-1149 G/T与RA风险之间的关系,这些样本包括3,405例RA病例和4,111例自称为“白色”欧洲血统的对照。使用三种基因分型平台之一对样品进行基因分型,并应用严格的质量控制指标。我们用双尾Cochran Mantel-Haenszel加性固定效应模型检验了相关性。在个体集合中,PRL-1149 T与RA风险之间关联的比值比范围为0.80至0.97。在所有四个集合的联合荟萃分析中,PRL-1149 T与RA风险之间关联的比值比为0.90(95% CI 0.84-0.96),p = 0.001。我们的研究结果表明PRL-1149 T等位基因与RA风险降低相关。效应量很小,但与其他与复杂性状相关的遗传多态性(包括RA)的比值比相似。进一步的研究将是必要的,以确认明确的关联。
Prior evidence demonstrates that the PRL -1149 T (minor) allele decreases prolactin expression and may be associated with autoimmune diseases. Our goal was to determine the role of the PRL -1149 G/T polymorphism (rs1341239) in rheumatoid arthritis (RA) susceptibility. We examined the association between PRL -1149 G/T and RA risk in four separate collections consisting of 3,405 RA cases and 4,111 controls of self-described “white” European ancestry. Samples were genotyped using one of three genotyping platforms, and strict quality control metrics were applied. We tested for association with a two-tailed Cochran Mantel-Haenszel additive, fixed effects model. In the individual collections, odds ratios for an association between PRL -1149 T and RA risk ranged from 0.80 to 0.97. In a joint meta-analysis across all four collections, the odds ratio for an association between PRL -1149 T and RA risk was 0.90 (95% CI 0.84-0.96) with p = 0.001. Our results suggest an association between the PRL -1149 T allele and decreased RA risk. The effect size is small but similar to odds ratios for other genetic polymorphisms associated with complex traits, including RA. Further studies will be necessary to confirm association unequivocally.
