Pyruvate dehydrogenase deficiency

Pyruvate Dehydrogenase Deficiency (PDHA) is a human genetic disease. It follows a sex-linked, dominant inheritance pattern, but is approximately equally prevalent in both males and females. It affects a gene which codes for a critical enzyme complex, the Pyruvate dehydrogenase complex (PDC) which links the metabolic pathways of Acetyl CoA

The citric acid cycle.

Presentation

PDHA causes lactate ratio. Symptoms are varied, and include developmental defects (especially of the brain and nervous system), muscular spasticity and early death.

Genetics

PDHA is most commonly linked to the alpha unit of E1, but recessive variants exist.
