    Slc2a13, a risk gene for Parkinson’s disease associated with Snca and Lrrk2

    JW. Li, GX. Zhang, T. Wang, ZC. Lin, N. Xiong (Wuhan, China)

    Objective: To exploit the potential function of the risk gene Slc2a13 in PD progression. Background: 越来越多的证据证实了总体遗传位点和候选基因对帕金森病的贡献,以及两个最确定的风险基因,即α-突触核蛋白(Snca)和富含亮氨酸的重复激酶2(Lrrk2)。Slc2a13 编码哺乳动物肌醇转运蛋白,被认为是一种群体依赖性风险基因。越来越多的证据支持这样一种观点,即 Slc2a13 活性的改变强调了 PD 的发展。剖析转运蛋白活性降低如何导致多巴胺能神经元变性和丧失,可能会进一步加深我们对功能的理解。 Method: A total of 338 cases…
