摘要:

目的 探讨亚甲基四氢叶酸还原酶(MTHFR)C677T基因多态性与高同型半胱氨酸血症(HHcy)及急性冠状动脉综合征(ACS)的关系。方法 采用聚合酶链反应(PCR)-芯片杂交法检测81例ACS患者[同型半胱氨酸(Hcy)正常患者51例、合并HHcy患者30例]及98名体检健康者(正常对照组)MTHFR C677T位点基因多态性,并分析其与HHcy及ACS发病易感性的关联。结果 ACS组和正常对照组基因型分布均符合Hardy-Weinberg遗传平衡原则。相对于正常对照组,MTHFR C677T位点TT基因型相对于CC基因型、TT基因型相对于CT+CC基因型、T等位基因相对于C等位基因,其发生ACS的OR值(95%CI)分别为2.60(1.12~6.03)、2.02(1.06~3.86)和1.66(1.09~2.53)。在ACS患者中,MTHFR C677T位点TT基因型相对于CT+CC基因型,发生HHcy的OR值(95%CI)为2.74(1.08~7.00)。结论 MTHFR C677T位点TT基因型是HHcy的危险因子,可增加 ACS的发病风险。

Abstract:

Objective To investigate the relations of methylenetetrahydrofolate reductase(MTHFR) gene C677T polymorphism with hyperhomocysteinemia(HHcy) and acute coronary syndrome(ACS). Methods A total of 81 patients with ACS,including 51 cases of normal homocysteine(Hcy) and 30 cases of HHcy,and 98 healthy subjects(healthy control group) were enrolled. The relations of MTHFR gene C677T polymorphism with HHcy and ACS susceptibility were analyzed. Results The distribution of genotypes in ACS group and healthy control group was in conformity with the principle of Hardy-Weinberg equilibrium. Compared to healthy control group,the odds ratios(OR) [95% confidence interval(CI)] for ACS of MTHFR gene C677T TT to CC,TT to CT+CC and T to C were 2.60(1.12-6.03),2.02(1.06-3.86) and 1.66(1.09-2.53),respectively. Furthermore,the OR(95%CI)for HHcy of MTHFR gene C677T TT to CT+CC was 2.74(1.08-7.00). Conclusions MTHFR gene C677T TT genotype is a risk factor for HHcy and may increase the risk of ACS.
