Summaries for CHRNE Gene

Entrez Gene Summary for CHRNE Gene

  • Acetylcholine receptors at mature mammalian neuromuscular junctions are pentameric protein complexes composed of four subunits in the ratio of two alpha subunits to one beta, one epsilon, and one delta subunit. The acetylcholine receptor changes subunit composition shortly after birth when the epsilon subunit replaces the gamma subunit seen in embryonic receptors. Mutations in the epsilon subunit are associated with congenital myasthenic syndrome. [provided by RefSeq, Sep 2009]

GeneCards Summary for CHRNE Gene

CHRNE (Cholinergic Receptor, Nicotinic, Epsilon (Muscle)) is a Protein Coding gene. Diseases associated with CHRNE include chrne-related congenital myasthenic syndrome and myasthenic syndrome, congenital, 4a, slow-channel. Among its related pathways are CREB Pathway and Nanog in Mammalian ESC Pluripotency. GO annotations related to this gene include extracellular ligand-gated ion channel activity and acetylcholine-activated cation-selective channel activity. An important paralog of this gene is CHRNA3.

  • Myasthenic syndrome, congenital, 4A, slow-channel (CMS4A) [MIM:605809]: 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. CMS4A is a slow-channel myasthenic syndrome. It is caused by kinetic abnormalities of the AChR, resulting in prolonged AChR channel opening episodes, prolonged endplate currents, and depolarization block. This is associated with calcium overload, which may contribute to subsequent degeneration of the endplate and postsynaptic membrane. {ECO:0000269 PubMed:12141316, ECO:0000269 PubMed:7531341, ECO:0000269 PubMed:7538206, ECO:0000269 PubMed:8872460}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Myasthenic syndrome, congenital, 4B, fast-channel (CMS4B) [MIM:616324]: 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. CMS4B is a fast-channel myasthenic syndrome. It is caused by kinetic abnormalities of the AChR, resulting in brief opening and activity of the channel, with a rapid decay in endplate current, failure to achieve threshold depolarization of the endplate and consequent failure to fire an action potential. {ECO:0000269 PubMed:10962020, ECO:0000269 PubMed:22592360, ECO:0000269 PubMed:8755487}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Myasthenic syndrome, congenital, 4C, associated with acetylcholine receptor deficiency (CMS4C) [MIM:608931]: 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. {ECO:0000269 PubMed:9158150}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Note=The muscle AChR is the major target antigen in the autoimmune disease myasthenia gravis. Myasthenia gravis is characterized by sporadic muscular fatigability and weakness, occurring chiefly in muscles innervated by cranial nerves, and characteristically improved by cholinesterase-inhibiting drugs.
