Carnitine-acylcarnitine translocase deficiency


See Disclaimer regarding information on this site. Some links on this page may take you to organizations outside of the National Institutes of Health.

Overview

Carnitine-acylcarnitine translocase deficiency is a condition that prevents the body from converting certain fats called long-chain fatty acids into energy, particularly during periods without food (fasting). Carnitine, a natural substance acquired mostly through the diet, is used by cells to process fats and produce energy. People with this disorder have a faulty transporter that disrupts carnitine's role in processing long-chain fatty acids.[1] Carnitine-acylcarnitine translocase deficiency is a type of fatty acid oxidation disorder. There are two forms of carnitine-acylcarnitine translocase deficiency. The most common type happens in newborns. A milder, less common type happens in older infants and children.[2]
