Structure and tissue distribution
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.[5]
Clinical significance
Mutations in this gene are associated with a number of movement disorders, most commonly paroxysmal kinesigenic dyskinesia where approximately 1/3 of cases will harbor mutations in PRRT2.[6][7] It has also been associated with episodic ataxias, and in particular in combination with various types of epilepsy.[8] Mutations in PRRT2 lead also to hemiplegic migraine.[9]
