Fatty oxidation disorder

A fatty-acid metabolism disorder is a defect in one of the enzymes involved in fatty acid metabolism.

They are sometimes classified with the lipid metabolism disorders, but in other contexts they are considered a distinct category.

Oxidation
The term fatty acid oxidation disorder (FAOD) is sometimes used, especially when there is an emphasis on the oxidation of the fatty acid.

In addition to the fetal complications, they can also cause complications for the mother during pregnancy.

Examples include:
 * trifunctional protein deficiency
 * MCADD, LCHADD, and VLCADD



Carnitine/transport
The fatty acids are transported by carnitine, and defects in this process are associated with several disorders. They involve the step immediately before oxidation, and are often grouped with the oxidation disorders.
