摘要
目的:探讨载脂蛋白E(ApoE)基因多态性与散发阿尔茨海默病(sporad ic A lzhe im er d isease,SAD)的关系。方法:通过DNA直接测序的方法检查30例SAD和30例正常老人ApoE基因的3个编码外显子。结果:ApoEε4等位基因频率(23.3%,8.3%)及ε4/4,ε3/4,ε2/4基因型合并后其基因型频率(40%,16.7%)在SAD和对照组之间有显著差异(2χ=5.065,P<0.05;2χ=4.022,P<0.05);SAD组ε2等位基因频率与对照组相比差异不明显。结论:结果提示ApoEε4等位基因为本地区老年人群的危险因素。
Objective: To study the association of polymorphism of ApoE gene with sporadic Alzheimer disease in Guizhou, China. Methods: Three exons of ApoE gene in 30 sporadic Alzheimer disease patients (SAD group) and 30 normol people (control group) were screened with DNA sequencing method. Results: The allelic frequencies of ApoEε4 (23.3%, 8.3% ) and genotype frequencies of ApoEε4/4, ε3/4, and ε2/4 in SAD group (40%, 16.7% ) were significantly higher than those of control group(X^2= 5. 065, P 〈0.05; X^2 =4. 022,P 〈0.05). Conclusion: The ApoEε4 alleles might be a genetic risk factor in the occurrence of SAD in Guizhou, China.
