Background
This gene encodes a member of a family of proteins that are receptor associated proteins of the synapse. The encoded protein contains a conserved cAMP-dependent protein kinase phosphorylation site, and plays a critical role in clustering and anchoring nicotinic acetylcholine receptors at synaptic sites by linking the receptors to the underlying postsynaptic cytoskeleton, possibly by direct association with actin or spectrin. Mutations in this gene may play a role in postsynaptic congenital myasthenic syndromes. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Function
disease:Defects in RAPSN are a cause of congenital myasthenic syndrome type 1d (CMS1D) [MIM:608931]; also called congenital myasthenic syndrome associated with acetylcholine receptor deficiency. Congenital myasthenic syndromes (CMS) are inherited disorders of neuromuscular transmission that stem from mutations in presynaptic, synaptic, or postsynaptic proteins. Postsynaptic disorders result from mutations in proteins forming the subunits of the muscle acetylcholine receptor (AChR). The kinetic abnormalities of AChR result in either prolonged ion channel activations that underlie "slow-channel myasthenic syndromes" (SCCMS) or abbreviated channel activations that underlie the abnormally rapid decay of endplate currents in "fast-channel syndromes" (FCCMS). CMS1D is the third disorder associated with postsynaptic CMS which could result from mutations in the proteins forming the muscle AChR.
