Carnitine Palmitoyl Transferase type I Deficiency (CPT-IA)


Carnitine palmitoyltransferase I deficiency (CPT-IA) is an inborn error of metabolism, an inherited condition in which the body is unable to break down certain fats, particularly during periods without enough food. It is considered a fatty acid oxidation condition because people affected by CPT-IA are unable to change some fats into the energy the body needs to function. This can cause too many unused fatty acids to build up in the body. Symptoms of CPT-IA can vary and may include poor feeding, low blood sugar (hypoglycemia), extreme tiredness/lethargy, liver problems, a high level of carnitine in the blood and/or other potential signs and symptoms. CPT-IA can be a life threatening condition. Support groups are available to help connect families living with CPT-IA deficiency with others who have experience or expertise with fatty acid oxidation conditions.
