Overview

Medium-chain acyl-coenzyme A dehydrogenase deficiency (MCADD) is an inherited metabolic disorder that prevents the body from converting certain fats to energy, particularly during periods without food (fasting). Normally, through a process called fatty acid oxidation, several enzymes work in a step-wise fashion to break down (metabolize) fats and convert them to energy. People with MCADD do not have enough of an enzyme needed for the step that metabolizes a group of fats called medium-chain fatty acids. MCADD is caused by mutations in the ACADM gene and is inherited in an autosomal recessive manner.[1] Treatment includes avoidance of fasting and of medium chain triglycerides in the diet.[2]
