How is VLCAD deficiency diagnosed?

A diagnosis of VLCAD deficiency may be suspected based on an abnormal newborn screen or the presence of characteristic signs and symptoms. In both of these cases, additional testing can then be ordered to further investigate the diagnosis. This testing may include specialized tests performed on a sample of blood, urine, skin cells, muscle, and/or liver tissue. Genetic testing for changes (mutations) in the ACADVL gene can confirm the diagnosis.[1][2]

Testing

  • The Genetic Testing Registry (GTR) provides information about the genetic tests for this condition. The intended audience for the GTR is health care providers and researchers. Patients and consumers with specific questions about a genetic test should contact a health care provider or a genetics professional.

Newborn Screening

  • An ACTion (ACT) sheet for this condition has been developed by experts in collaboration with the American College of Medical Genetics, an organization providing education, resources and a voice for the medical genetics profession. ACT sheets are general guidelines that describe the short-term actions a health professional should follow in talking with the family and deciding the appropriate steps in the follow-up of an infant who has screened positive on a newborn screening test. Click on the link above to view the ACT sheet.
  • An Algorithm for this condition has been developed by experts in collaboration with the American College of Medical Genetics, an organization providing education, resources and a voice for the medical genetics profession. Algorithms are general guidelines for healthcare providers outlining steps involved in determining the diagnosis of an infant who has screened positive on a newborn screening test.
