摘要
目的探讨多巴胺D3受体(DRD3)基因Ser9Gly多态性与中国帕金森病抑郁的相关性。方法 2016年6月至2018年6月,散发帕金森病患者312例根据汉密尔顿抑郁量表评分分为抑郁组(n=132)和非抑郁组(n=180)。同时招募性别和年龄匹配的健康体检者252例为对照组。留取外周血提取基因组DNA,采用限制性片段长度多态性-聚合酶链反应和限制性酶切方法检测DRD3基因Ser9Gly多态位点。结果三组DRD3基因Ser9Gly位点基因型和等位基因型分布无显著性差异(χ~2=3.095,χ~2=2.627, P> 0.05)。结论 DRD3基因Ser9Gly多态性并非中国帕金森病抑郁人群的遗传易感因素。
Objectives To explore the relationship between the dopamine D3 receptor(DRD3) polymorphism on Ser9 Gly and depression in Parkinson's disease(PD).Methods From June, 2016 to June, 2018, 312 Chinese patients with PD were divided into depression group(n = 132)and non-depression group(n = 180) according to scores of Hamilton Depression Scale. A total of 252 age-and gender-matched healthy subjects were recruited as control group. Their blood samples were collected. Genotyping of Ser9 Gly polymorphism was carried out using polymerase chain reaction-restriction fragment length polymorphism.Results No statistical difference was identified in Ser9 Gly polymorphism among three groups in both gene types and allel(χ~2 = 3.095, χ~2 = 2.627, P > 0.05).Conclusion Ser9 Gly polymorphism in DRD3 gene may not be a susceptible factor for depression in PD in China.
