What is the official name of the CPT2 gene?
The official name of this gene is “carnitine palmitoyltransferase 2.”
CPT2 is the gene's official symbol. The CPT2 gene is also known by other names, listed below.

What is the normal function of the CPT2 gene?
The CPT2 gene provides instructions for making an enzyme called carnitine palmitoyltransferase 2. This enzyme is essential for fatty acid oxidation, a multistep process that breaks down (metabolizes) fats and converts them into energy. Fatty acid oxidation takes place within mitochondria, which are the energy-producing centers in cells. A group of fats called long-chain fatty acids must be attached to a substance known as carnitine to enter mitochondria. Once these fatty acids are inside mitochondria, carnitine palmitoyltransferase 2 removes the carnitine and adds a substance called coenzyme A. Long-chain fatty acids must be joined to coenzyme A before they can be metabolized to produce energy. Fatty acids are a major source of energy for the heart and muscles. During periods of fasting, fatty acids are also an important energy source for the liver and other tissues.
