Epilepsie révélant une chorée-acanthocytose: à propos d’un cas

Chorea-acanthocytosis (ChAc) is an extremely rare autosomal recessive disorder caused by mutations in the VSP13A gene on chromosome 9q21. It is characterized by neurological symptoms, psychiatric manifestations and multisystem involvement resulting in myopathy, axonal neuropathy and presence of spiculated red blood cells or acanthocytes. Rarely, epilepsy may be the early symptom in these patients. This can lead to serious delays in diagnosis. We here report the case of a patient with this disease who had seizures several years before the onset of typical manifestations.
