Myasthenic Syndrome, Congenital, 19; Cms19

Description

Congenital myasthenic syndrome-19 is an autosomal recessive disorder resulting from a defect in the neuromuscular junction, causing generalized muscle weakness, exercise intolerance, and respiratory insufficiency. Patients present with hypotonia, feeding difficulties, and respiratory problems soon after birth, but the severity of the weakness and disease course is variable (summary by Logan et al., 2015).For a discussion of genetic heterogeneity of CMS, see CMS1A (OMIM ).
