Very Long-Chain Acyl-CoA Dehydrogenase (VLCAD) Deficiency

Very long-chain acyl-CoA dehydrogenase deficiency (VLCAD) is an autosomal recessive, rare disorder of fatty acid oxidation. Presentation is variable, and has been classified into three forms: a severe neonatal form with high mortality and hypertrophic cardiomyopathy, hepatomegaly and hypotonia, a milder childhood form with hypoketotic hypoglycemia, hepatomegaly and hypotonia, and an adult-onset form with isolated skeletal muscle involvement, leading to muscle pain, rhabdomyolysis or myoglobinuria.
