newborn screening programme


MCADD stands for medium-chain acyl-CoA dehydrogenase deficiency. It is the most common disease in a group called fatty acid oxidation disorders. People with MCADD are unable to break down certain chemicals the body uses to release energy. People with MCADD are usually healthy if they are treated with a strict diet. However, infections or prolonged fasting can lead to drowsiness, coma or sudden death.
