摘要
目的探讨中国人种Saitohin基因(STH)Q7R多态性与肌萎缩侧索硬化(amyotrophic lateral sclerosis,ALS)的发病相关性。方法采用病例对照研究,应用递减聚合酶链式反应限制性酶切片段长度多态性(Touchdown-PCR-RFLP)方法检测135例ALS患者和135例正常人STH基因Q7R多态性。结果所有DNA样本的STH基因均为QQ型纯合子。结论STH基因Q7R多态性与ALS无相关性。
Objective To evaluate the association between the Q7R polymorphism of saitohin gene(STH) and amyotrophic lateral sclerosis. Methods The Q7R polymorphism was examined in 270 subjects (ALS: 135; controls: 135) from China,by the Touchdown polymerase chain reaction restriction fragment length polyrnorphism(Touchdown PCR -RFLP). Results Only QQ homozygote was found in the all subjects. Conclusion The results indicated that the Q7R polymorphism of STH gene was not associated with ALS.
