Abstract

The genetic architecture of amyotrophic lateral sclerosis (ALS) is being increasingly understood. In this far-reaching review, we examine what is currently known about ALS genetics and how these genes were initially identified. We also discuss the various types of mutations that might underlie this fatal neurodegenerative condition and outline some of the strategies that might be useful in untangling them. These include expansions of short repeat sequences, common and low-frequency genetic variations, de novo mutations, epigenetic changes, somatic mutations, epistasis, oligogenic and polygenic hypotheses. This article is part of a Special Issue entitled ALS complex pathogenesis.

摘要

肌萎缩侧索硬化症(ALS)的遗传结构正逐渐为人所知。在这篇影响深远的综述中,我们审视了目前关于ALS遗传学的已知信息以及这些基因最初是如何被鉴定出来的。我们还讨论了可能是这种致命神经退行性疾病基础的各种类型的突变,并概述了一些可能有助于理清这些突变的策略。这些策略包括短重复序列的扩增、常见和低频遗传变异、新生突变、表观遗传变化、体细胞突变、上位性、寡基因和多基因假说。本文是名为“ALS复杂发病机制”的特刊的一部分。
