Her initial blood glucose concentration was 2 mg/dL. She had a hepatomegaly of 3 cm, and her liver enzyme levels were moderately elevated. Intravenous glucose was begun and the child was alert by 24 hours. At age 36 months the child again became obtunded during the course of an intercurrent upper respiratory tract infection.

Her older sibling, who was asymptomatic, was also found to be carnitine
