Summaries for Myasthenic Syndrome, Congenital, 4c, Associated with...

UniProtKB/Swiss-Prot : 73 Myasthenic syndrome, congenital, 4C, associated with acetylcholine receptor deficiency: A form of congenital myasthenic syndrome, a group of disorders characterized by failure of neuromuscular transmission, including pre- synaptic, synaptic, and post-synaptic disorders that are not of autoimmune origin. Clinical features are easy fatigability and muscle weakness affecting the axial and limb muscles (with hypotonia in early-onset forms), the ocular muscles (leading to ptosis and ophthalmoplegia), and the facial and bulbar musculature (affecting sucking and swallowing, and leading to dysphonia). The symptoms fluctuate and worsen with physical effort. CMS4C is an autosomal recessive disorder of postsynaptic neuromuscular transmission, due to deficiency of AChR at the endplate that results in low amplitude of the miniature endplate potential and current.

MalaCards based summary : Myasthenic Syndrome, Congenital, 4c, Associated with Acetylcholine Receptor Deficiency, also known as congenital myasthenic syndrome 4c, is related to congenital myasthenic syndrome associated with acetylcholine receptor deficiency and myasthenic syndrome, congenital, 11, associated with acetylcholine receptor deficiency, and has symptoms including ophthalmoparesis, muscle cramp and facial paresis. An important gene associated with Myasthenic Syndrome, Congenital, 4c, Associated with Acetylcholine Receptor Deficiency is CHRNE (Cholinergic Receptor Nicotinic Epsilon Subunit), and among its related pathways/superpathways are PAK Pathway and RNA Polymerase II Transcription Initiation And Promoter Clearance. The drugs Selenium and Trace Elements have been mentioned in the context of this disorder. Affiliated tissues include skeletal muscle and tongue, and related phenotypes are mandibular prognathia and dental malocclusion

Disease Ontology : 12 A congenital myasthenic syndrome characterized by autosomal recessive inheritance of postsynaptic neuromuscular junction defects, early-onset muscle weakness, and low amplitude of the miniature endplate potential and current that has material basis in homozygous or compound heterozygous mutation in the CHRNE gene on chromosome 17p13.

OMIM : 56 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. Patients with mutations in the CHRNE gene may have compensatory increased expression of the fetal subunit CHRNG (100730) and may respond to treatment with cholinergic agents, pyridostigmine, or amifampridine (summary by Engel et al., 2015). For a discussion of genetic heterogeneity of CMS, see CMS1A (601462). (608931)
