Functioni

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.

Pathology & Biotechi

Involvement in diseasei

Multiple pterygium syndrome, lethal type (LMPS)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionMultiple 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.
See also OMIM:253290
Multiple pterygium syndrome, Escobar variant (EVMPS)2 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionNon-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.
