PRRT2 is the gene recently associated with paroxysmal kinesigenic dyskinesia (PKD), benign familial infantile epilepsy, and choreoathetosis infantile convulsions. We report four family members with PRRT2 mutations who had heterogeneous paroxysmal disorders. The index patient had transient infantile paroxysmal torticollis, then benign infantile epilepsy that responded to carbamazepine. The index patients father had PKD and migraine with aphasia, and his two brothers had hemiplegic migraine with onset in childhood. All four family members had the same PRRT2 c.649dupC mutation. We conclude that heterogeneous paroxysmal disorders are associated with PRRT2 mutations and include paroxysmal torticollis and hemiplegic migraine. We propose that PRRT2 is a new gene for hemiplegic migraine.
