Function

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. {ECO:0000269PubMed:19081061, ECO:0000269PubMed:7782287}.

Subcellular Localization

Mitochondrion matrix.

Disease Associations

Pyruvate dehydrogenase E1-alpha deficiency (PDHAD) [MIM:312170]: An enzymatic defect causing primary lactic acidosis in children. It is associated with a broad clinical spectrum ranging from fatal lactic acidosis in the newborn to chronic neurologic dysfunction with structural abnormalities in the central nervous system without systemic acidosis. {ECO:0000269PubMed:1293379, ECO:0000269PubMed:1338114, ECO:0000269PubMed:1551669, ECO:0000269PubMed:1909401, ECO:0000269PubMed:7545958, ECO:0000269PubMed:7573035, ECO:0000269PubMed:7757088, ECO:0000269PubMed:7887409, ECO:0000269PubMed:7967473, ECO:0000269PubMed:8032855, ECO:0000269PubMed:8504306, ECO:0000269PubMed:8664900, ECO:0000269PubMed:8844217, ECO:0000269PubMed:9671272}. Note=The disease is caused by mutations affecting the gene represented in this entry.Leigh syndrome, X-linked (X-LS) [MIM:308930]: A X-linked form of Leigh syndrome, an early-onset progressive neurodegenerative disorder characterized by the presence of focal, bilateral lesions in one or more areas of the central nervous system including the brainstem, thalamus, basal ganglia, cerebellum, and spinal cord. The lesions are areas of demyelination, gliosis, necrosis, spongiosis, or capillary proliferation. Clinical symptoms depend on which areas of the central nervous system are involved and include psychomotor retardation, hypotonia, ataxia, weakness, vision loss, eye movement abnormalities, seizures, dysphagia, and lactic acidosis. Note=The disease is caused by mutations affecting the gene represented in this entry.
