Large-scale SNP analyses conducted on subjects in a Parkinson's disease patient group and a normal control group led to the successful identification of a gene (GRK5) associated with Parkinson's disease. In addition, it was newly discovered that phosphorylation of α-synuclein is promoted by enhanced expression of the GRK5 gene, and as a result, the formation of soluble α-synuclein oligomers is promoted, leading to Parkinson's disease. The present invention enables the assessment of Parkinson's disease as well as the screening of therapeutic agents for Parkinson's disease using as an index the expression of GRK5 gene.
通过对帕
金森病患者组和正常对照组的受试者进行大规模 SNP 分析,成功鉴定出与帕
金森病相关的
基因(GRK5)。此外,还新发现 GRK5
基因的表达增强会促进 α-突触核蛋白的
磷酸化,从而促进可溶性 α-突触核蛋白寡聚体的形成,导致帕
金森病。本发明能够以 GRK5
基因的表达量为指标,对帕
金森病进行评估,并筛选出治疗帕
金森病的药物。
