We reported a male infant with multiple acyl CoA dehydrogenase deficiency, probably due to electron transfer flavoprotein dehydrogenase deficiency. He was noted to have severe muscle weakness, a high serum creatine kinase (CK) level up to 6920 IU/L, lipid storage myopathy and fatty liver at 6 months of age. A GC/MS analysis of urinary organic acids showed excess excretion of dicarboxylic acids, including glutaric, 2-hydroxyglutaric, adipic, suberic, sebacic, malonic, ethylmalonic and methylsuccinic acids. On a urinary acylglycine analysis, hexanoylglycine and suberylglycine were increased, but not isovalerylglycine, in amount. No ketosis was noted. The muscle pathology showed increased oil-red O positive lipid droplets of various sizes indicative of lipid storage myopathy. There was diffuse decrease in the activity of cytochrome c oxidase. No ragged-red fibers were noted. His clinical symptoms improved remarkably after the administration of riboflavin (100 mg/day) and L-carnitine (1000 mg/day). He was then diagnosed as having probable riboflavin-responsive multiple acyl-CoA dehydrogenase deficiency. The glutaryl CoA dehydrogenase activity in lymphocytes was normal, as were the alpha- and beta-subunits of electron transfer flavoprotein. These findings led us to suspect electron transfer flavoprotein dehydrogenation deficiency. Although he had several episodes of short-term deterioration in clinical and laboratory findings, he developed normally with normal intelligent till 10 years of age.
