Summaries for CHAT Gene

Entrez Gene Summary for CHAT Gene

  • This gene encodes an enzyme which catalyzes the biosynthesis of the neurotransmitter acetylcholine. This gene product is a characteristic feature of cholinergic neurons, and changes in these neurons may explain some of the symptoms of Alzheimer's disease. Polymorphisms in this gene have been associated with Alzheimer's disease and mild cognitive impairment. Mutations in this gene are associated with congenital myasthenic syndrome associated with episodic apnea. Multiple transcript variants encoding different isoforms have been found for this gene, and some of these variants have been shown to encode more than one isoform. [provided by RefSeq, May 2010]

GeneCards Summary for CHAT Gene

CHAT (Choline O-Acetyltransferase) is a Protein Coding gene. Diseases associated with CHAT include myasthenic syndrome, congenital, 6, presynaptic and myasthenic syndrome, congenital, 1a, slow-channel. Among its related pathways are Circadian entrainment and Glycerophospholipid biosynthesis. GO annotations related to this gene include transferase activity, transferring acyl groups and choline O-acetyltransferase activity. An important paralog of this gene is CRAT.

CLAT_HUMAN
  • Myasthenic syndrome, congenital, 6, presynaptic (CMS6) [MIM:254210]: 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. CMS6 affected individuals have myasthenic symptoms since birth or early infancy, negative tests for anti-AChR antibodies, and abrupt episodic crises with increased weakness, bulbar paralysis, and apnea precipitated by undue exertion, fever, or excitement. CMS6 inheritance is autosomal recessive. {ECO:0000269 PubMed:11172068, ECO:0000269 PubMed:12756141}. Note=The disease is caused by mutations affecting the gene represented in this entry.
