摘要
目的:研究慢性肾脏病非透析患者Klotho基因启动子区域G-395A单核苷酸多态性的分布,探讨该基因多态性位点与慢性肾脏病动脉硬化的相关性。方法:116例慢性肾脏病非透析患者均进行彩超测定颈动脉内膜厚度,并记录动脉硬化的传统危险因素,根据测定结果分为动脉硬化组(56例)和对照组(60例)。应用Taq Man探针等位基因特异性杂交分析法对Klotho基因G-395A多态性位点进行分析。结果:G-395A多态性位点共检测出GG、GA、AA 3种基因型,频率分别为56.9%、32.8%和10.3%,符合Hardy-Weinberg平衡。动脉硬化组G-395A等位基因的频率显著低于对照组(35.1%vs49.0%,P=0.032)。logistic回归分析,调整传统危险因素后G-395A与动脉硬化呈负相关(β=-0.412,P=0.024)。结论:Klotho基因G-395A等位基因可能是慢性肾脏病动脉硬化的遗传学保护因素。
Objective:To investigate the distribution of G - 395A polymorphism in promoter of Klotho gene in Chronic Kid-ney Disease Patients and analyze its association with arteriosclerosis. Methods:Genotyping of G - 395A polymorphism was performed in 56 arteriosclerotic patients of CKD and 60 controls using an allelic discrimination assay with TaqMan probes. Carotid artery intima- media thickness and atherosclerotic plaques were measured as a marker of atherosclerotic vascular damage. Results:Genotype fre-quencies of GG,GA and AA were 56. 9% . 32. 8% and10. 3% respectively. The distribution was in accordance with Hardy - Weinberg equilibrium. The frequency of the A allele carriers was signif - icantly lower in the arteriosclerosis group than in the control group (35. 1% vs 49. 0% ,P ﹤ 0. 05). Logistic regression analysis revealed that after adjusted for traditional risk factors,the Aallele was negatively correlated with arteriosclerosis(β = - 0. 412,P ﹤ 0. 05). Conclusion:The A allele of G - 395A polymorphism of Klotho gene may be a protective factor against arteriosclerosis in CKD patients.
