What is pyruvate dehydrogenase deficiency?

Also known as: pyruvate dehydrogenase complex deficiency, PDCD, PDHC, PDH deficiency, and others.

Depending on the availability of food, the body either uses glucose produced by the breakdown of ingested carbohydrates, when food is plentiful, or fat when food is limited, to produce the energy cells need to function.

The pyruvate dehydrogenase complex of three enzymes is the bridge that gives the body the flexibility to switch from one source of energy to the other. PDC deficiency is a disorder resulting from a lack of one of the three enzymes.
