Tests & Diagnosis
On this page
Genetic testing for carnitine-acylcarnitine translocase deficiency can be done on a blood sample. Genetic testing, also called DNA testing, looks for changes in the pair of genes that cause carnitine-acylcarnitine translocase deficiency. In some affected children, both gene changes can be found. However, in other children, neither or only one of the two gene changes can be found, even though we know they are present. DNA testing is not necessary to diagnose carnitine-acylcarnitine translocase deficiency, however, it can be helpful for carrier testing or prenatal diagnosis.

- 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.
- An ACTion (ACT) sheet is available for this condition that describes the short-term actions a health professional should follow when an infant has a positive newborn screening result. ACT sheets were developed by experts in collaboration with the American College of Medical Genetics.
- An Algorithm flowchart is available for this condition for determining the final diagnosis in an infant with a positive newborn screening result. Algorithms are developed by experts in collaboration with the American College of Medical Genetics.
- Baby's First Test is the nation's newborn screening education center for families and providers. This site provides information and resources about screening at the local, state, and national levels and serves as the Clearinghouse for newborn screening information.
- The Newborn Screening Coding and Terminology Guide has information on the standard codes used for newborn screening tests. Using these standards helps compare data across different laboratories. This resource was created by the National Library of Medicine.
- The Screening, Technology, and Research in Genetics (STAR-G) Project was a multi-state collaborative effort to obtain research data, identify strategies, and develop written materials for addressing the financial, ethical, legal and social issues surrounding the use of tandem mass spectrometry for newborn screening. As part of the STAR-G Project, fact sheets on newborn screening disorders have been developed for parents.
