Clinical characteristics: Multiple acyl-CoA dehydrogenase deficiency (MADD) represents a clinical spectrum in which presentations can be divided into type I (neonatal onset with congenital anomalies), type II (neonatal onset without congenital anomalies), and type III (late onset). MCAD deficiency is present from birth and is a lifelong condition. This site needs JavaScript to work properly. Proline hydroxylase is also involved in O 2 -sensing by HIF-1α.

A possible genetic defect in riboflavin transport of metabolism in the mother is postulated to be the cause of the transient MADD seen in the infant. The affected child inherits two copies of the abnormal gene — one from each parent. Another brother had been long-chain acyl-CoA synthetase to form the fatty acyl-CoA ester. Though both parents are carriers — each one has an abnormal gene — they typically don't have symptoms of the condition. A 12‐year‐old girl was shown to have carnitine‐deficient lipid storage myopathy and organic aciduria compatible with multiple acylcoenzyme A (acyl‐CoA) dehydrogenase deficiency.
