摘要: 阿尔茨海默病(Alzheimer's disease,AD)又称老年性痴呆,是老年人常见的神经系统变性疾病。AD的病因很复杂,但年龄老化与遗传因素为众所共识的病因。目前作用明确的与AD发生相关的基因主要有淀粉样前体蛋白基因、早老素-1基因、早老素-2基因和载脂蛋白E基因,而这4种基因的遗传特性只能解释很少部分AD发病,这就提示还有其他遗传因素参与AD的发病。本文综述了近10年来一些主要的AD候选基因的研究进展。

Abstract: Alzheimer's disease is a genetically complex disorder, and to date, three genes〔those that encode amyloid precursor protein(APP) and the presenilins(PS1 and PS2)〕 have been found to cause earlyonset familial AD and one genetic risk factor that encodes apolipoprotein E(APOE) lead to lateonset AD. In addition to the mutations in 4 known genes associated with AD, mutations in other genes may be implicated in the pathogenesis of the disease. A large number of studies that aimed to help uncover the remaining disease-related loci have been published in recent decades. The search continues for the discovery of additional genetic influences. Here we provide a review on some main AD candidate genes.
