Abstract:
Medium-chain acyl coenzyme A dehydrogenase (MCAD) deficiency is the most common of the inborn errors of mitochondrial fatty acid beta-oxidation. A male infant was born at 39 weeks of gestation following an uneventful pregnancy. He was discharged at age 28 h after a normal first-day check, but was subsequently re-admitted and died aged 44 h. Post-mortem blood and bile spot carnitine analysis revealed a profile consistent with MCAD deficiency. MCAD genotyping revealed 985 A to G (K329E) homozygosity. This is the first confirmed case of neonatal death due to MCAD deficiency in the UK.

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Pyruvate Oxidation
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...
