[Early Diagnosis of Chorea-Acanthocytosis: Orofacial Dyskinesia, Epileptic Seizures, and HyperCKemia].

Chorea-acanthocytosis is an uncommon neurodegenerative disorder. Early diagnosis is often challenging. The triad of orofacial dyskinesia, epileptic seizures, and hyperCKemia should alert neurologists of a neuroacanthocytosis syndrome. The diagnosis can be confirmed by detection of chorein deficiency or through molecular genetics (VPS13A mutation).
