摘要: 目的 研究新疆地区哈萨克族心房颤动与钾离子通道KCNE1-G38S基因多态性的相关性。方法 收集新疆地区哈萨克族房颤人群(房颤组)和非房颤人群(对照组)各100例的外周血样标本,提取DNA,经聚合酶链反应-限制性内切酶片段长度多态性(PCR-RFLP)、琼脂糖电泳法鉴定分析KCNE1-G38S基因型和等位基因分布。结果 KCNE1-G38S基因AA、AG、GG基因型频率在房颤组分别为O.13(13/100)、O.34(34/100)和O.53(53/100),在对照组分别为0.10(10/100)、O.57(57/100)和O.33(33/100),两组基因型分布有显著性差异(P<0.05),且房颤组G等位基因频率(O.70)明显高于对照组(0.515)(P<0.001)。结论:新疆地区哈萨克族心房颤动的发生与KCNEl-G38S基因多态性相关,KCNEl-G38S基因多态性位点可能存在种族、地区差异。

Abstract: Objective Research in xinjiang region kazak atrial fibrillation and potassium ion channels KCNE1-G38S genetic polymorphism of relevancy. Methods Collect the xinjiang region kazak atrial fibrillation (af group) and the crowd of people atrial fibrillation (control group) the 100 cases of peripheral blood sample specimens, extract DNA, the polymerase chain reaction-extinction enzymes fragment length polymorphism (PCR-RFLP), agarose electrophoresis analysis method appraisal KCNE1-G38S genotype and allelic distribution. Results KCNE1-G38S gene AA, AG, GG genotype frequency respectively in atrial fibrillation group 0.13 (13/100), 0. 34 (34/100) and 0.53 (53/100), in the control group were 0.10 (10/100), 0. 57 (57/100) and 0.33 (33/100), two groups of genotype distribution are statistically significant differences (P<0.05), and atrial fibrillation group G allele frequency (0.70) was much higher than those in the control group (0.515) (P<0.001). Conclusion Xinjiang region kazak the occurrence of af and KCNEl-G38S gene polymorphism related, KCNEl-G38S gene polymorphism site may exist race, regional differences.
