Abstract
Ethylmalonic encephalopathy (EE) is a rare autosomal recessive disorder characterized by early onset encephalopathy, chronic diarrhoea, petechiae, orthostatic acrocyanosis and defective cytochrome c oxidase (COX) in muscle and brain. High levels of lactic, ethylmalonic and methylsuccinic acids are detected in body fluids. EE is caused by mutations in ETHE1 gene, a mitochondrial sulfur dioxygenase. Neurologic signs and symptoms include progressively delayed development, hypotonia, seizures, and abnormal movements. We report on the clinical, electroencephalographic and MRI findings of a baby with a severe early onset encephalopathy associated with novel ETHE1 gene mutation. This is the first case described in literature with an early pure epileptic onset, presenting with West syndrome.
