摘要
目的 探讨重庆地区汉族人醛糖还原酶基因启动区 (C 10 6T)单核苷酸多态性与糖尿病肾病的关系。方法 用聚合酶链反应 ,琼脂糖凝胶电泳和限制性内切酶BfaⅠ对 192例重庆地区汉族 2型糖尿病人的 (C 10 6T)等位基因和基因型频率进行分析。结果 2型糖尿病伴白蛋白尿患者C等位基因和CC基因型频率较正常白蛋白尿糖尿病患者显著增加。Logistic回归分析显示 ,C等位基因和CC基因型在 2型糖尿病中与糖尿病肾病有关 ,P值分别为 0 .0 3 2和 0 .0 46。结论 AR基因启动区 (C 10 6T)单核苷酸多态性与中国汉族 2型糖尿病患者糖尿病肾病的发生有一定关联 ,可能是糖尿病肾病的功能性多态性和遗传标志之一。
Objective To study the relationship between the (C 106T) single nucleotide polymorphsim of promoter region of aldose reductase gene and type 2 diabetes mellitus with nephropathy in Chinese Han from Chongqing. Methods The (C 106T) allele and genotype of 192 patients of type 2 diabetes were examined by polymerase chain reaction agarose gel electrophoresis and restriction enzyme Bfa Ⅰ. Results The frequencies of both allele C and genotype CC were significantly higher in type 2 diabetes patients with albuminuria than in those without albuminuria. Logistic regression analysis showed that allele C and genotype CC were associated with diabetic nephropathy in type 2 diabetes mellitus patients( P =0.032 and 0.046, respectively). Conclusion This finding suggests that (C 106T) single nucleotide polymorphism in the aldose reductase gene promoter region may be associated with diabetic nephropathy of Chinese Han type 2 diabetes. It may be a functional polymorphism and can serve as an inherited marker for susceptibility of diabetic nephropathy.
