摘要

高同型半胱氨酸血症是心血管疾病、肥胖和2型糖尿病的危险因素,在这些代谢紊乱的高风险人群中很普遍。我们评估了北印度人同型半胱氨酸代谢相关基因的常见变异或其水平与2型糖尿病、肥胖和相关性状的关系。我们在初始阶段(2.115名受试者)对90个变异进行了基因分型,并在独立样本集(2.085名受试者)中复制了top信号。变异MTHFR-rs1801133是与2型糖尿病相关的最高信号(OR = 0.78 (95% CI = 0.67-0.92), P = 0.003),在对照组中也与负荷后2小时血浆葡萄糖(P = 0.04)、高密度脂蛋白胆固醇(P = 0.004)和总胆固醇(P = 0.01)相关。在荟萃分析后,这些关联既不重复也不显著。在排除这些重要的候选基因在2型糖尿病、肥胖和相关性状中的作用之前,需要进行涉及更大研究人群和不同种族群体的研究。

Common variants of homocysteine metabolism pathway genes and risk of type 2 diabetes and related traits in Indians.

Hyperhomocysteinemia, a risk factor for cardiovascular disorder, obesity, and type 2 diabetes, is prevalent among Indians who are at high risk of these metabolic disorders. We evaluated association of common variants of genes involved in homocysteine metabolism or its levels with type 2 diabetes, obesity, and related traits in North Indians. We genotyped 90 variants in initial phase (2.115 subjects) and replicated top signals in an independent sample set (2.085 subjects). The variant MTHFR-rs1801133 was the top signal for association with type 2 diabetes (OR = 0.78 (95%  CI = 0.67-0.92), P = 0.003) and was also associated with 2 h postload plasma glucose (P = 0.04), high-density lipoprotein cholesterol (P = 0.004), and total cholesterol (P = 0.01) in control subjects. These associations were neither replicated nor significant after meta-analysis. Studies involving a larger study population and different ethnic groups are required before ruling out the role of these important candidate genes in type 2 diabetes, obesity, and related traits.
