3-Methylcrotonyl-CoA carboxylase(MCC) is a biotin-dependent enzyme involved in the leucine metabolism. We describe a patient with MCC deficiency who manifested with Reye syndrome-like illness with status epilepticus, metabolic acidosis, hypoglycemia, hyperammonemia, elevated liver enzymes and neurologic impairments after a viral gastroenteritis and then suffered from Lennox-Gastaut syndrome. Urinary organic acid analysis revealed increased excretions of 3-hydroxyisovaleric acid and 3-methylcrotonylglycine. This patient was managed with a leucine restriction diet and supplementation of biotin and carnitine, which was not so effective. He suffered from neurologic sequelae such as Lennox-Gastaut syndrome, motor and cognitive impairements.
