Medium-chain acyl-CoA dehydrogenase deficiency (MCAD deficiency or MCADD) is a disorder of fatty acid oxidation that impairs the body's ability to break down medium-chain fatty acids into acetyl-CoA. The disorder is characterized by hypoglycemia and sudden death without timely intervention, most often brought on by periods of fasting or vomiting.
Avoidance of fasting periods, high-fat diets, and dehydration is recommended for those who are affected. A diet consisting of low-fat intake and supplemental calories is common for management of VLCAD deficiency. If a metabolic crisis is not treated, a child with VLCAD can develop: breathing problems, seizures, coma, sometimes leading to death.
The primary treatment method for fatty-acid metabolism disorders is dietary modification. It is essential that the blood-glucose levels remain at adequate levels to prevent the body from moving fat to the liver for energy. This involves snacking on low-fat, high-carbohydrate nutrients every 2–6 hours.
Problems related to 3-hydroxyacyl-coenzyme A dehydrogenase deficiency can be triggered by periods of fasting or by illnesses such as viral infections. This disorder is sometimes mistaken for Reye syndrome, a severe disorder that may develop in children while they appear to be recovering from viral infections such as chicken pox or flu. Most ...
E.g., reduction of dietary protein remains a mainstay of treatment for phenylketonuria and other amino acid disorders; Dietary supplementation or replacement E.g., oral ingestion of cornstarch several times a day helps prevent people with glycogen storage diseases from becoming seriously hypoglycemic.

The probe began in 2022 as child welfare advocates called for increased oversight of youth treatment centers following high-profile incidents of abuse and deaths at facilities around the country.
The mutation is recessive, and often parents of children who have the deficiency can be diagnosed afterward as carriers. [3] In humans the most common naturally occurring mutation in MCAD is located at amino acid residue Lys-304. [1] The altered residue occurs as a result of a single-point mutation in which the lysine side chain is replaced by ...
Diagnoses are typically made based on newborn screening done from blood obtained using a heel prick at birth. Prior to widespread inclusion of FAO (fatty acid oxidation) disorders in newborn screening tests, diagnosis typically occurred as a result of children presenting for medical attention having hypoglycemic hypoketotic crisis.
