Pyruvate dehydrogenase deficiency (also known as pyruvate dehydrogenase complex deficiency or PDCD or PDH deficiency) is a rare neurodegenerative disorder associated with abnormal mitochondrial metabolism. PDCD is a genetic disease resulting from mutations in one of the components of the pyruvate dehydrogenase complex (PDC). [1]
Pyruvate dehydrogenase (PDH) deficiency is a congenital degenerative metabolic disease resulting from a mutation of the pyruvate dehydrogenase complex (PDC) located on the X chromosome. While defects have been identified in all 3 enzymes of the complex, the E1-α subunit is predominantly the culprit.
While pyruvate dehydrogenase deficiency is rare, there are a variety of different genes when mutated or nonfunctional that can induce this deficiency. First, the E1 subunit of pyruvate dehydrogenase contains four different subunits: two alpha subunits designated as E1-alpha and two beta subunits designated as E1-beta.
Pyruvate dehydrogenase deficiency (PDH) is a genetic disease resulting in lactic acidosis as well as neurological dysfunction in infancy and early childhood. Typically PDH is the result of a mutation in the X-linked gene for the E1 subunit of the pyruvate dehydrogenase complex.
Pyruvate dehydrogenase E1 component subunit alpha, somatic form, mitochondrial is an enzyme that in humans is encoded by the PDHA1 gene.The pyruvate dehydrogenase complex is a nuclear-encoded mitochondrial matrix multienzyme complex that provides the primary link between glycolysis and the tricarboxylic acid (TCA) cycle by catalyzing the irreversible conversion of pyruvate into acetyl-CoA.
For children, the FDA has approved the use of synthetic HGH to treat growth hormone deficiency (GHD), being born small for gestational age, idiopathic short stature, chronic renal insufficiency ...
All of the pyruvate dehydrogenase isozymes have been associated with various metabolic disorders, including diabetes. This is due to a mechanism by which consistently elevated free fatty acid levels stimulate the PDK enzymes, particularly, PDK2 and PDK4 in the liver. In stimulating this activity, there is less PDH activity, and therefore less ...
First, it’s important to understand that inflammation isn’t always bad. “Inflammation is one of the body’s key mechanisms for maintaining homeostasis, acting as a natural response to ...
