what is mcadd disease
Medium-chain acyl-coenzyme A dehydrogenase deficiency. From Wikipedia, the free encyclopedia. Medium-chain acyl-CoA dehydrogenase deficiency, often known as MCAD deficiency or MCADD is a disorder of fatty acid oxidation that impairs the body's ability to break down medium-chain fatty acids into acetyl-CoA.CADD is most prevalent in individuals of Northern European Caucasian descent, with an incidence of 1:4000 to 1:17,000 depending on the population. Treatment of MCADD is mainly preventative, by avoiding fasting and other situations where the body relies on fatty acid oxidation to supply energy.
