Abstract
Menkes disease is an X-linked recessive disorder affecting copper metabolism due to an inactivating mutation of ATP7A gene. This result in loss of copper intestinal absorption, tissue deficiency and failure in multiple essential copper-enzyme systems such as the cytochrome c oxidase. Symptoms usually occur during the first months of life with neurological signs such as epilepsy associated to other signs among them typical hair appearance. We report the case of a 3 month-old infant hospitalized due to partial tonic-clonic seizures. Laboratory findings showed increased of lactates in blood and in cerebrospinal fluid. First screenings for infectious, metabolic and genetic causes were negative. After recurrence of multifocal seizures further investigations are made according to the presence of thick and tortuous hair. Low levels of ceruloplasmin and copper in plasma are in agreement with the suspected diagnosis of Menkes disease. Molecular analysis of the ATP7A gene confirmed the diagnosis with a non-sens mutation.
