Finally, mutations in PRRT2 have been found in a number of paroxysmal disorders, including paroxysmal kinesigenic dyskinesia (PKD, MIM #128200), infantile convulsions with PKD (PKD/IC, MIM #602066), benign familial infantile epilepsy (BFIE, MIM #605751), and episodic ataxia or febrile seizures, apart from HM (Wood 2012). Here, PRRT2 is linked to episodic kinesigenic dyskinesia 1.
