Abstract
Ethylmalonic encephalopathy (EE) is an autosomal recessive devastating metabolic disorder affecting the brain, gastrointestinal tract, peripheral vessels and rarely the other vascular organs. We report a 10-month-old girl who presented as a meningococcemia clinic but later diagnosed ethylmalonic encephalopathy. Molecular analyses revealed a homozygous c.554 T > G; p. L185R mutation in ETHE1 gene. She was only partially benefited from riboflavine, coenzyme Q10, metronidazole, N-acetylcysteine and symptomatic treatment and discharged from hospital with the sequela of oxygene dependance and developmental delay. We observed N-acetylcysteine 100 mg/kg/day intravenous infusion theraphy may be the most important drug especially in comatous EE patients.
