A 12‐year‐old girl was shown to have carnitine‐deficient lipid storage myopathy and organic aciduria compatible with multiple acylcoenzyme A (acyl‐CoA) dehydrogenase deficiency. In muscle mitochondria, activities of both short‐chain acyl‐CoA dehydrogenase (SCAD) and medium‐chain acyl‐CoA dehydrogenase (MCAD) were 35% of normal. Antibodies against purified SCAD, MCAD, and electron‐transfer flavoprotein were used for detection of cross‐reacting material (CRM) in the patient's mitochondria… 

Late‐onset riboflavin‐responsive myopathy with combined multiple acyl coenzyme A dehydrogenase and respiratory chain deficiency

It is concluded that some lipid storage myopathies can show dramatic response to riboflavin, and rib oflavin treatment in a 69-year-old patient with late-onset myopathy dramatically improved and morphologic changes in muscle disappeared.

Hereditary protein C deficiency associated with riboflavin‐responsive lipid storage myopathy

The treatment was found to restore fatty acid oxidation in fresh muscle homogenate, deficient acylCoA‐dehydrogenases in mitochondria and decrease lipid droplets.

Stridor as the major presenting symptom in riboflavin-responsive multiple acyl-CoA dehydrogenation deficiency

Treatment with 200 mg of riboflavin per day led to a dramatic clinical improvement with restoration of normal respiration and an increase in muscular tone within 2 months, and metabolite excretion in urine completely normalized.

ETFDH mutations as a major cause of riboflavin-responsive multiple acyl-CoA dehydrogenation deficiency.

This is the largest collection of riboflavin-responsive MADD patients ever reported, and the first demonstration of the molecular genetic basis for the disorder.

Riboflavin therapy. Biochemical heterogeneity in two adult lipid storage myopathies.

Plasma acyl-carnitine and urinary organic acid profiles indicated multiple acyl coenzyme A dehydrogenase deficiency, which was mild in patient 1 and severe in patient 2, and biochemical parameters were either totally or partly corrected after riboflavin therapy.

The abnormal metabolites-adipic, suberic, and sebacic acids-were detected in large amounts in the urine of a boy during a Reye's syndrome-like crisis, suggesting a flavineadeninedinucleotide-related acyl-CoA dehydrogenation defect as the cause of the disease.

Systemic carnitine deficiency due to lack of electron transfer flavoprotein

Carnitine acts as a buffer for excessive accumulation of intramitochondrial acyl CoAs, and defective β-oxidation can cause carnitine insufficiency, and defects in the ETF-QO defect caused massive urinary excretion of the short-chain acylcarnitines that accumulated in mitochondria.
