Abstract

Spinocerebellar ataxia type 17 (SCA17) is a hereditary neurodegenerative disorder characterized by progressive motor and cognitive decline, leading to severe disability and death. SCA17 is caused by a CAG repeat expansion mutation in the TBP gene, resulting in the production of an abnormally long polyglutamine tract, which classifies it as a polyglutamine disorder. At present, there is no effective treatment for SCA17, and existing therapies provide only symptomatic relief. While the exact pathogenic mechanisms of SCA17 remain unclear, the TBP mutation affects a well-characterized transcription factor, making it an ideal model for studying polyglutamine-related neurodegeneration. Here, we review the clinical features of SCA17 and explore proposed mechanisms of its pathogenesis.

脊髓小脑共济失调17型的分子机制
脊髓小脑性共济失调17型(SCA17)是一种遗传性神经退行性疾病,以进行性运动和认知能力下降为特征,可导致严重残疾和死亡。SCA17是由TBP基因的CAG重复扩增突变引起的,导致产生异常长的聚谷氨酰胺束,这将其归类为聚谷氨酰胺疾病。目前,还没有针对SCA17的有效治疗方法,现有的治疗方法仅提供症状缓解。虽然SCA17的确切致病机制尚不清楚,但TBP突变影响一种特性良好的转录因子,使其成为研究聚谷氨酰胺相关神经变性的理想模型。在这里,我们回顾了SCA17的临床特征,并探讨了其发病机制。

期刊介绍: Molecular Neurobiology is an exciting journal for neuroscientists needing to stay in close touch with progress at the forefront of molecular brain research today. It is an especially important periodical for graduate students and "postdocs," specifically designed to synthesize and critically assess research trends for all neuroscientists hoping to stay active at the cutting edge of this dramatically developing area. This journal has proven to be crucial in departmental libraries, serving as essential reading for every committed neuroscientist who is striving to keep abreast of all rapid developments in a forefront field. Most recent significant advances in experimental and clinical neuroscience have been occurring at the molecular level. Until now, there has been no journal devoted to looking closely at this fragmented literature in a critical, coherent fashion. Each submission is thoroughly analyzed by scientists and clinicians internationally renowned for their special competence in the areas treated.
