PRRT2 mutations are involved in many disorders including PKC, benign familial infantile epilepsy (BFIE, MIM 605751), infantile convulsions with choreoathetosis (ICCA, MIM 602066) [23], hemiplegic and regular migraines, paroxysmal non-kinesigenic dyskinesia (PNKD), paroxysmal exertion-induced dyskinesia (PED), childhood absence epilepsy, febrile seizures both in family cases [24] and sporadic cases [25] and episodic ataxia [26]. Here, PRRT2 is linked to childhood absence epilepsy.
