Genes affected

RAPSN (HGNC:9863): (receptor associated protein of the synapse) 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.

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jan 25, 2024	This variant occurs in a non-coding region of the RAPSN gene. It does not change the encoded amino acid sequence of the RAPSN protein. This variant is present in population databases (rs786200905, gnomAD 0.06%). This variant has been observed in individual(s) with congenital myasthenic syndrome (PMID: 12651869, 15145336, 19620612, 22326364). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 8051). Studies have shown that this variant alters RAPSN gene expression (PMID: 12651869, 15282317). For these reasons, this variant has been classified as Pathogenic. -
