Description

Congenital myasthenic syndrome associated with AChR deficiency is a disorder of the postsynaptic neuromuscular junction (NMJ) clinically characterized by early-onset muscle weakness with variable severity. Electrophysiologic studies show low amplitude of the miniature endplate potential (MEPP) and current (MEPC) resulting from deficiency of AChR at the endplate. Treatment with acetylcholinesterase inhibitors or amifampridine may be helpful (summary by Engel et al., 2015).For a discussion of genetic heterogeneity of CMS, see CMS1A (OMIM ).
