title: Dicarboxylicaciduria and secondary carnitine deficiency in glycogenosis type IV.
abstract: A 3 year old boy developed an unusually mild form of glycogen storage disease type IV. Metabolic investigations showed severe abnormalities of fatty acid and carnitine metabolism. A muscle carnitine deficiency was found. Treatment with L-carnitine orally led to a notable improvement in muscle strength.
