Myasthenic Syndrome, Congenital, 15; Cms15

Description

Congenital myasthenic syndrome-15 is one of a heterogeneous group of disorders that arise from impaired signal transmission at the neuromuscular synapse and are characterized by fatigable muscle weakness (summary by Cossins et al., 2013).For a discussion of genetic heterogeneity of CMS, see CMS1A (OMIM ).
