Myasthenic Syndrome, Congenital, 13; Cms13

Description

Congenital myasthenic syndrome-13 is an autosomal recessive neuromuscular disorder characterized by onset of proximal muscle weakness in the first decade. EMG classically shows a decremental response to repeated nerve stimulation. Affected individuals show a favorable response to acetylcholinesterase (AChE) inhibitors (summary by Belaya et al., 2012).For a discussion of genetic heterogeneity of CMS, see CMS1A (OMIM ).
