摘要:

原发性进行性失语(PPA)是一种常见的退行性神经系统性言语障碍疾病。早期研究初步发现大脑水平的致病原因;而基于基因技术研究发现,约20%~30%患者存在常染色体显性遗传,C9基因突变是导致与肌萎缩性脊髓侧索硬化症、额颞叶痴呆等PPA类相关疾病的因素,C9基因重复序列扩增可能干扰C9基因表达,阻断RNA结合蛋白,并破坏RNA功能。

Abstract:

Primary progressive aphasia (PPA) is a common neurodegenerative speech disease. Earlier studies on PPA merely observed preliminary pathogenic factors at the brain level. Based on genetic technology, almost 20% to 30% patients with autosomal dominant inheritance reveals that this deficit is closely relevant to gene mutation. C9 gene mutation is the primary factor related to amyotrophic lateral sclerosis and frontotemporal dementia, which is attributed to the main causes of PPA. Repeating expansion of C9 gene may influence the expression of C9 gene, block the combination of RNA and protein, and destroy RNA function.

Key words: primary progressive aphasia, genetic language disorders, amplification of repetitive sequences of gene, review
