Summaries for CHRNG Gene

Entrez Gene Summary for CHRNG Gene

  • The mammalian muscle-type acetylcholine receptor is a transmembrane pentameric glycoprotein with two alpha subunits, one beta, one delta, and one epsilon (in adult skeletal muscle) or gamma (in fetal and denervated muscle) subunit. This gene, which encodes the gamma subunit, is expressed prior to the thirty-third week of gestation in humans. The gamma subunit of the acetylcholine receptor plays a role in neuromuscular organogenesis and ligand binding and disruption of gamma subunit expression prevents the correct localization of the receptor in cell membranes. Mutations in this gene cause Escobar syndrome and a lethal form of multiple pterygium syndrome. Muscle-type acetylcholine receptor is the major antigen in the autoimmune disease myasthenia gravis.[provided by RefSeq, Sep 2009]

GeneCards Summary for CHRNG Gene

CHRNG (Cholinergic Receptor, Nicotinic, Gamma (Muscle)) is a Protein Coding gene. Diseases associated with CHRNG include escobar syndrome and chrng-related disorders. Among its related pathways are CREB Pathway and Nanog in Mammalian ESC Pluripotency. GO annotations related to this gene include acetylcholine-activated cation-selective channel activity and channel activity. An important paralog of this gene is CHRNA3.

(2) OMIM Diseases for CHRNG Gene (100730)


  • Multiple pterygium syndrome, lethal type (LMPS) [MIM:253290]: Multiple pterygia are found infrequently in children with arthrogryposis and in fetuses with fetal akinesia syndrome. In lethal multiple pterygium syndrome there is intrauterine growth retardation, multiple pterygia, and flexion contractures causing severe arthrogryposis and fetal akinesia. Subcutaneous edema can be severe, causing fetal hydrops with cystic hygroma and lung hypoplasia. Oligohydramnios and facial anomalies are frequent. {ECO:0000269 PubMed:16826520, ECO:0000269 PubMed:16826531}. Note=The disease is caused by mutations affecting the gene represented in this entry.
  • Multiple pterygium syndrome, Escobar variant (EVMPS) [MIM:265000]: Non-lethal form of arthrogryposis multiplex congenita. It is an autosomal recessive condition characterized by excessive webbing (pterygia), congenital contractures (arthrogryposis), and scoliosis. Variable other features include intrauterine death, congenital respiratory distress, short stature, faciocranial dysmorphism, ptosis, low-set ears, arachnodactyly and cryptorchism in males. Congenital contractures are common and may be caused by reduced fetal movements at sensitive times of development. Possible causes of decreased fetal mobility include space constraints such as oligohydramnion, drugs, metabolic conditions or neuromuscular disorders including myasthenia gravis. {ECO:0000269 PubMed:16826520, ECO:0000269 PubMed:16826531}. Note=The disease is caused by mutations affecting the gene represented in this entry.
