摘要: 目的  系统评价DRD3基因Ser9Gly多态性与特发性震颤的相关性。方法  计算机检索pubmed、Web of Science、中国知网(Chinese National Knowledge Infrastructure, CNKI)、维普数据库、中国生物医学文献数据库、万方数据库,收集2019年10月前有关DRD3基因Ser9Gly多态性与特发性震颤的病例-对照研究。应用统计学软件Stata14.0进行Meta分析。结果  共纳入8项病例-对照研究,病例组1456例,对照组1651例。Meta分析结果显示,显性模型中GG+GA基因型的群体发病风险高于AA基因型的群体[OR=1.16,95%CI(1.00,1.35),P=0.043]。基于人种的亚组分析显示,DRD3基因Ser9Gly多态性与特发性震颤之间的相关性仅存在于高加索人群中。结论  高加索人群中DRD3基因Ser9Gly多态性与特发性震颤具有相关性,且GG+GA基因型的存在增加发病风险。

Abstract: Objective  To systematically review the correlation between DRD3 Ser9Gly variant and the risk of essential tremor.Methods  PubMed,  Web of Science,  CNKI,  WanFang Data,  VIP database and Chinese Biomedical Literature Database were searched to collect case  control studies on the DRD3 Ser9Gly polymorphism and primary open angle glaucoma from inception to September 30th,  2019. Two reviewers independently screened literature,  extracted data and assessed the risk of bias of included studies. Meta analysis was performed by Stata 14.0 software. Results   A total of 8 studies were included,  which involved 1 456  cases and 1 651 controls. The results of meta analysis showed that  individuals that carried GG+GA genotype risked more with essential tremor than those carried AA genotype (OR=1.16, 95%CI[1.00, 1.35], P=0.043);Subgroup analysis based on race showed that significant correlation between DRD3 Ser9Gly polymorphism and essential tremor risk in the Asians and Caucasians. Conclusion  DRD3 Ser9Gly polymorphism is significantly associated with susceptibility to   essential tremor among Caucasian population,  and more risk may exist in individuals that carried GG+GA genotype.
