Malonyl-CoA decarboxylase deficiency
Malonyl-coenzyme A decarboxylase deficiency
Initial symptoms/signs may include:
- poor feeding
- lactic acidosis
- Contact the family and evaluate the infant for vomiting, poor feeding, lethargy, ketonuria
- Provide emergency treatment/referral for evidence of hypoglycemia, acidosis, seizures
- 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
- Support implementation and maintenance of a high carbohydrate, low fat diet with medium chain triglyceride supplements
- Oral L-carnitine is indicated
- Prompt treatment of infections/fever/gastroenteritis with IV fluids containing glucose and hospital admission
- For those identified after irreversible consequences, assist in management, particularly with developmental and educational interventions

Use of a long-chain triglyceride-restricted/medium-chain triglyceride-supplemented diet in a case of malonyl-CoA decarboxylase deficiency with cardiomyopathy.
J Inherit Metab Dis. 2010;. PubMed abstract
Malonic aciduria, is a rare inborn error of metabolism characterised by a variable phenotype of developmental delay, seizures, cardiomyopathy and acidosis. This case of malonic aciduria with cardiomyopathy demonstrates improvement in cardiac function attributable to LCT-restricted/MCT-supplemented diet.
