Short-Chain Acyl-CoA Dehydrogenase (SCAD) Deficiency

Short-chain acyl-CoA dehydrogenase deficiency (SCAD) is a rare disorder of fatty acid oxidation. The presentation is variable, but the phenotype commonly includes one or more of the following: developmental delay, seizures, hypotonia, hypoglycemia, and/or failure to thrive. Some individuals are not identified until later childhood or as adults, when signs of muscle weakness and progressive myopathy may occur.
