肌萎缩侧索硬化症(ALS)是一种典型的神经退行性疾病,其特征是大脑和脊髓中的运动神经元进行性病变。虽然DNA测序技术筛查出众多的ALS致病基因,拓宽了人们对ALS疾病发生的认识,但是这些功能各异的基因导致ALS疾病进程的分子机制仍是有待阐明的。随着基础研究的不断进展,人们发现线粒体的损伤,线粒体的动力学异常以及线粒体自噬等与神经退行性疾病如ALS的发病具有重要联系。在本篇综述中,我们主要讨论了ALS致病基因导致线粒体功能障碍的可能机制,旨在强调线粒体功能障碍在ALS疾病发展中的重要作用。

家族性肌萎缩侧索硬化症10型的临床特征和基因突变分析 [PDF]
【目的】探讨家族性肌萎缩侧索硬化症10型患者的临床特点、分子遗传学特征。【方法】对2013年中山大学附 属第一医院神经科门诊就诊发现的该病家系行高通量测序法检测其TARDBP基因外显子突变类型。【结果】该家系中3代共 5例患者,每代均有患者且男女都有发病,符合常染色体显性遗传特征。该家系患者于50岁左右起病,病情进展迅速,从出 现临床症状到最终死亡仅为8~18个月左右。TARDBP基因检测结果显示,先证者的exon6发生了c.892 G>A的杂合突变, 另在第3代家系其他成员中 ...
