Summary of DLAT
This gene encodes an enzyme that is part of a complex that plays an important role in the pathways that convert the energy from food into a form that cells can use (R).
The Function of DLAT
The pyruvate dehydrogenase complex catalyzes the overall conversion of pyruvate to acetyl-CoA and CO(2), and thereby links the glycolytic pathway to the tricarboxylic cycle.

Advanced Summary
Leigh syndrome Genetics Home Reference provides information about Leigh syndrome. pyruvate dehydrogenase deficiency At least two mutations in the DLAT gene have been identified in individuals with pyruvate dehydrogenase deficiency; mutation of the DLAT gene is a very rare cause of this condition. Pyruvate dehydrogenase deficiency is characterized by a potentially life-threatening buildup of a chemical called lactic acid in the body (lactic acidosis), delayed development, and neurological problems. Mutations in the DLAT gene lead to an abnormal E2 enzyme and reduced activity of the pyruvate dehydrogenase complex, although the mechanism is unclear. With decreased activity of this complex, pyruvate builds up and is converted, in another chemical reaction, to lactic acid, causing lactic acidosis. In addition, the production of cellular energy is diminished. The brain, which is especially dependent on this form of energy, is severely affected, resulting in the neurological problems associated with pyruvate dehydrogenase deficiency.
The DLAT gene provides instructions for making the E2 enzyme (also known as dihydrolipoamide acetyltransferase), which is part of a large group of proteins called the pyruvate dehydrogenase complex. This complex comprises multiple copies of three enzymes, including E2, and several related proteins. The E2 enzyme is the core to which the other proteins attach to form the complex. The pyruvate dehydrogenase complex plays an important role in the pathways that convert the energy from food into a form that cells can use. This complex converts a molecule called pyruvate, which is formed from the breakdown of carbohydrates, into another molecule called acetyl-CoA. The E2 enzyme performs one part of this chemical reaction. The conversion of pyruvate is essential to begin the series of chemical reactions that produces adenosine triphosphate (ATP), the cell's main energy source.
