摘要
目的研究中国帕金森病患者儿茶酚-O-甲基转移酶(eatechol-O-methyltransferase,COMT)及单胺氧化酶B(monoamineoxidaseB,MAOB)基因的多态性分布。方法研究对象为由中国帕金森病研究协作组收集的来自全国共29个研究中心的1408例帕金森病患者。抽取静脉血提取基因组DNA,应用DNA自动测序仪,采用Sanger双脱氧链终止法检测COMT和MAOB的基因型。结果COMTrs4680AA、AG、GG基因型的频率分别为8.9%、42.0%、49.1%;COMTrs4818CC、CG、GG基因型的频率分别为42.5%、45.6%、11.9%;MAOBrs1799836A/AA、AG、G/GG基因型的频率分别为74,4%、14.1%、11.5%;COMTrs4680和MAOBrs1799836基因型同时为高活性的比例为36.86%。结论中国帕金森病患者COMT及MAOB基因多态性分布特点具有其独特特征,可能与帕金森病患者药物疗效差异存在一定的相关性。
Objective To study polymorphisms of catechol-O-methyhransferase (COMT) and monoamine oxidase B (MAO-B) genes among Chinese patients with Parkinson' s disease. Methods Genotypes of the COMT and MAO-B genes of 1408 patients with Parkinson's disease was sequenced using Sanger method. And these patients were recruited by Chinese Parkinson Study Group from 29 research centers throughout the country. Results The genotypic frequencies of COMT rs4680 AA, AG, GG were 8. 9% ,42.0% and 49.1%. Those of rs4818 CC, CG, GG were 42. 5%, 45.6% and 11.9%, respectively. The genotype frequencies of MAO-B rs1799836 A/AA, AG, G/GG were 74.4%, 14. 1% and 11. 5%, respectively. The haplotype formed by COMT rs4680 (GG) and MAOB rs1799836 (A/AA) genotype has a frequency of 36.86 %. Conclusion Polymorphisms of COMT and MAO-B genes has a unique characteristics among Chinese patients with Parkinson's disease. They may be related with differences in drug response in such patients.
