About This Section

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 (muscle)) is a protein-coding gene. Diseases associated with CHRNB1 include slow-channel congenital myasthenic syndrome, and cystic lymphangioma, and among its related super-pathways are Nanog in Mammalian ESC Pluripotency and Class A/1 (Rhodopsin-like receptors). GO annotations related to this gene include acetylcholine-activated cation-selective channel activity and channel activity. An important paralog of this gene is CHRNA5.

UniProtKB/Swiss-Prot: ACHB_HUMAN, P11230
Function: 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, slow-channel (SCCMS) [MIM:601462]: A common congenital myasthenic
    syndrome. Congenital myasthenic syndromes are characterized by 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. Congenital myasthenic syndrome slow-channel type is caused by kinetic
    abnormalities of the AChR, resulting in prolonged endplate currents and prolonged AChR channel opening episodes.
    Note=The disease is caused by mutations affecting the gene represented in this entry
  • Myasthenic syndrome, congenital, associated with acetylcholine receptor deficiency (CMS-ACHRD)
    [MIM:608931]: A post-synaptic congenital myasthenic syndrome. Congenital myasthenic syndromes (CMS) are inherited
    disorders of neuromuscular transmission that stem from mutations in presynaptic, synaptic, or postsynaptic
    proteins. Note=The disease is caused by mutations affecting the gene represented in this entry
