Abstract
Background: Paroxysmal kinesigenic dyskinesia (PKD) is a rare condition associated with heterozygous mutations in the proline-rich transmembrane protein 2 (PRRT2) gene.
Phenomenology Shown: In this article we illustrate the phenomenology of PKD in a male previously misdiagnosed with Tourette’s syndrome.
Educational Value: Regardless of the underlying phenotype, PKD is highly responsive to some antiepileptic drugs.
