Short-chain acyl-CoA deficiency (SCADD)
Short chain acyl-CoA dehydrogenase deficiency
Acyl-CoA dehydrogenase short chain (ACADS)
277.85, Disorders of fatty acid oxidation
- Hypoketotic hypoglycemia
Subsequent symptoms may occur including:
- Failure to thrive
- Muscle weakness
- Developmental delay,
- Metabolic acidosis
An adult form of SCADD affects only the muscles and may cause:
- Pain and weakness, especially after exertion
- Episodes of nausea, vomiting, and shortness of breath
Milder variants of this condition are very frequent in the general population and usually do not require treatment. Even severe forms usually cause no symptoms even though they might aggravate co-existing conditions.
Treatment consists of carnitine supplementation, low-fat diet and fasting avoidance. Again, this is rarely needed.
- Contact the family and evaluate the infant for poor feeding, vomiting, lethargy
- Provide emergency treatment/referral for signs or symptoms of hypoglycemia, lethargy, metabolic acidosis (see for additional information)
- To confirm the diagnosis, work with the following service(s): see all Newborn Screening Programs services providers (3) in our database
- For evaluation and ongoing collaborative management, consult the following service(s): Pediatric Medical Genetics , (801-213-3599); See also Services below
- Educate the family regarding signs, symptoms, and the need for urgent care when the infant becomes ill (see Short-Chain Acyl-CoA Deficiency Info for Parents (STAR-G) for additional information)
- Support the implementation of frequent, low fat, high carbohydrate meals
- Oral L-carnitine and riboflavin may be indicated for some children
