Talk with your doctor about what to do if symptoms develop. Causes. When you don't have enough of the MCAD enzyme in your body, certain fats called medium-chain fatty acids can't be broken down and converted to energy. This results in hypoglycemia and low energy. Also, fatty acids can build up in body tissues and cause damage to the liver and brain. MCAD deficiency is inherited from both parents. Though both parents are carriers - each one has an abnormal gene - they typically don't have symptoms of the condition. – MCAD can cause bouts of illness called Metabolic Crises.
