MYASTHENIC SYNDROME, CONGENITAL, 2C, ASSOCIATED WITH ACETYLCHOLINE RECEPTOR DEFICIENCY; CMS2C
Description
Congenital myasthenic syndrome associated with AChR deficiency is a disorder of the postsynaptic neuromuscular junction (NMJ) characterized clinically 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 cholinesterase inhibitors or amifampridine may be helpful (summary by Engel et al., 2015).For a discussion of genetic heterogeneity of CMS, see CMS1A (OMIM ).
Most common symptoms of MYASTHENIC SYNDROME, CONGENITAL, 2C, ASSOCIATED WITH ACETYLCHOLINE RECEPTOR DEFICIENCY; CMS2C
- Muscle weakness
- Feeding difficulties
- Respiratory insufficiency
- Myopathy
- Neonatal hypotonia

MYASTHENIC SYNDROME, CONGENITAL, 2A, SLOW-CHANNEL; CMS2A
Description
Slow-channel congenital myasthenic syndrome (SCCMS) is a disorder of the postsynaptic neuromuscular junction (NMJ) characterized by early-onset progressive muscle weakness. The disorder results from kinetic abnormalities of the acetylcholine receptor channel, specifically from prolonged opening and activity of the channel, which causes prolonged synaptic currents resulting in a depolarization block. This is associated with calcium overload, which may contribute to subsequent degeneration of the endplate and postsynaptic membrane. Treatment with quinine, quinidine, or fluoxetine may be helpful; cholinesterase inhibitors and amifampridine should be avoided (summary by Engel et al., 2015).For a discussion of genetic heterogeneity of CMS, see CMS1A (OMIM ).
Most common symptoms of MYASTHENIC SYNDROME, CONGENITAL, 2A, SLOW-CHANNEL; CMS2A
- Short stature
- Muscle weakness
- Ptosis
- Flexion contracture
- High palate
