Ethylmalonic Encephalopathy (Epema Syndrome; EE) is a rare autosomal recessive disorder caused by a mutation in the ETHE1 gene which codes for protein ETHE1. A deficiency of this protein inhibits proper energy production in mitochondria and a deficiency in cytochrome c oxidase. This results in accumulation of 2-methylbutyrylglycine, N-butyrylglycine, isobutyrylglycine, isovalerylglycine, and methylsuccinic acid in urine. Concentrations of L-carnitine are reduced in plasma. Symptoms, which present at birth, include peripheral neuropathy, seizures, microcephaly, and hypotonia lead to premature death. Treatment includes riboflavin and L-carnitine.
