Pathogenic variants of PRRT2 are associated with a large spectrum of familial neurological disorders: PRRT2 is primarily associated with paroxysmal dyskinesia (PKD) but also hemiplegic migraine (HM), infantile convulsions and choreoathetosis (ICCA) and benign sporadic and familial seizures (BFIS) (84, 85). The gene discussed is PRRT2; the disease is Choreoathetosis.
