摘要先天性肌无力综合征(CMS)是一组由遗传缺陷导致的神经肌肉信息传递障碍疾病，属于神经肌肉接头疾病。主要表现为骨骼肌疲劳性肌无力，大多数发病年龄早，常见死因为呼吸衰竭，致残率高。随着基因测序技术的提高及有关致病蛋白结构和功能的深入研究，过去20多年来对该病的发病机制有了更多认识，早期诊断和治疗可明显改善患者的症状。现针对CMS的病因、临床特点及诊疗等方面的研究进展进行综述。

abstractsCharacterized by impaired neuromuscular transmission, congenital myasthenic syndromes (CMS) are a group of genetic disorders.The main manifestations include fatigue and weakness of skeletal muscle, with most onset in infant or early childhood.The common cause of death is respiratory failure, with high disability rate.With the improvement of gene sequencing technology and the in-depth study on the structure and function of pathogenic proteins, the pathogenesis of the disease has been deeply understood in the past 20 years.Early diagnosis and treatment can significantly improve the symptoms in patients.In this manuscript, the etiology, clinical characteristics, diagnosis and treatment of CMS are reviewed.
