This gene encodes a transmembrane protein containing a proline-rich domain in its N-terminal half. Studies in mice suggest that it is predominantly expressed in brain and spinal cord in embryonic and postnatal stages. Mutations in this gene are associated with episodic kinesigenic dyskinesia-1. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jan 2012]

A study in rhesus macaques identified the PRRT2 as a shared downregulated differentially expressed gene in left ventricular tissue between animals with hypertrophic cardiomyopathy and pediatric human HCM cases [Rivas et al. DOI:10.1038/s41598-024-82770-4].
