跳远运动员血管紧张素转化酶基因插入／缺失多态性研究

摘要

目的：研究汉族跳远运动员血管紧张素转化酶（ACE）基因插入／缺失（I／D）多态分布特点。方法采用PCR扩增、DNA测序、Hardy‐Weinberg遗传平衡定律、SPSS统计学分析跳远运动员ACE基因I／D多态性特点，并与普通人群。结果ACE基因16号存在II、DD、ID3种，Hardy‐Weinberg检验结果显示该研究受试对象具有群体代表性。跳远运动员ACE基因DD型和D等位基因明显高于普通汉族人群（P＜0．05）。结论ACE基因DD型和D等位基因可作为跳远运动员遗传选材的分子标记。%Objective To explore the characteristic of ACE gene I/D polymorphism in Han broad jumpers .Methods Distribu‐tion of ACE gene I/D polymorphism for broad jumpers was analyzed by PCR ,DNA sequencing ,Hardy‐Weinberg and SPSS ,and the results were compared with that of normal people .Results There were II ,DD and ID in gene ACE 16 ,and the Hard‐Weinberg re‐sults showed that the subjects were group representative .The ACE DD genotype and D allele in broad jumpers was statistically higher than normal controls (P<0 .05) .Conclusion The results suggest that ACE DD genotype and D allele are associated with training sensitivity of broad jumpers and could be the molecular marker for athletes choosing genetically .
