Summaries for CHRNB1 Gene

Entrez Gene Summary for CHRNB1 Gene

  • The muscle acetylcholine receptor is composed of five subunits: two alpha subunits and one beta, one gamma, and one delta subunit. This gene encodes the beta subunit of the acetylcholine receptor. The acetylcholine receptor changes conformation upon acetylcholine binding leading to the opening of an ion-conducting channel across the plasma membrane. Mutations in this gene are associated with slow-channel congenital myasthenic syndrome. [provided by RefSeq, Jul 2008]

GeneCards Summary for CHRNB1 Gene

CHRNB1 (Cholinergic Receptor Nicotinic Beta 1 Subunit) is a Protein Coding gene. Diseases associated with CHRNB1 include Myasthenic Syndrome, Congenital, 2A, Slow-Channel and Myasthenic Syndrome, Congenital, 2C, Associated With Acetylcholine Receptor Deficiency. Among its related pathways are Nanog in Mammalian ESC Pluripotency and Succinylcholine Pathway, Pharmacokinetics/Pharmacodynamics. GO annotations related to this gene include extracellular ligand-gated ion channel activity and channel activity. An important paralog of this gene is CHRNG.

UniProtKB/Swiss-Prot for CHRNB1 Gene

  • After binding acetylcholine, the AChR responds by an extensive change in conformation that affects all subunits and leads to opening of an ion-conducting channel across the plasma membrane.

  • Myasthenic syndrome, congenital, 2A, slow-channel (CMS2A) [MIM:616313]: 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. CMS2A 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:27375219, ECO:0000269 PubMed:8651643, ECO:0000269 PubMed:8872460}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Myasthenic syndrome, congenital, 2C, associated with acetylcholine receptor deficiency (CMS2C) [MIM:616314]: 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. CMS2C 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. CMS2C is clinically characterized by early-onset muscle weakness with variable severity. {ECO:0000269 PubMed:10562302}. Note=The disease is caused by mutations affecting the gene represented in this entry.
