What is MCAD in a baby?

Medium chain acyl CoA dehydrogenase deficiency (MCAD) is the most common inborn error of fatty acid oxidation. This condition may lead to cellular energy shortage and cause severe clinical events such as hypoketotic hypoglycemia, Reye syndrome and sudden death.

What are the symptoms of MCAD?

Symptoms

• Vomiting.
• Low energy (lethargy) or being overly sleepy (somnolent)
• Weakness or low muscle tone (hypotonia)
• Low blood sugar (hypoglycemia)
• Trouble breathing or fast breathing (tachypnea)
• Liver abnormalities (enlargement, high liver enzymes)
• Seizures.

Is MCAD treatable?

Newborn screening at birth allows MCAD deficiency to be diagnosed and treated early, before symptoms occur, preventing complications. Once identified, the disorder can be managed through diet and lifestyle. The main goal of treatment for MCAD deficiency is to prevent problems caused by hypoglycemia from occurring.

Is MCAD hereditary?

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. The affected child inherits two copies of the abnormal gene — one from each parent.

What changes happen in patients with MCAD disease?

MCAD deficiency impairs the energy supply to peripheral tissues through ketogenesis and increases glucose dependency and utilization. This results in hypoketotic hypoglycemia, metabolic acidosis, liver disease, and lethargy, which progress to coma and death when glycogen stores are depleted.

Is MCAD in newborn screening?

MCAD deficiency is diagnosed through newborn screening followed by genetic testing. Newborn screening. In the U.S., all states screen for MCAD deficiency at birth. If screening levels are abnormal, additional testing can be done.
