Numerous genetic disorders are caused by errors in fatty acid metabolism. These disorders may be described as fatty oxidation disorders or as a lipid storage disorders, and are any one of several inborn errors of metabolism that result from enzyme defects affecting the ability of the body to oxidize fatty acids in order to produce energy within muscles, liver, and other cell types.

Some of the more common fatty acid metabolism disorders are:
Coenzyme A dehydrogenase deficiencies
edit- Very long-chain acyl-coenzyme A dehydrogenase deficiency (VLCAD) - Very long-chain acyl-coenzyme A dehydrogenase
- Long-chain 3-hydroxyacyl-coenzyme A dehydrogenase deficiency (LCHAD) - Long-chain 3-hydroxyacyl-coenzyme A
- Medium-chain acyl-coenzyme A dehydrogenase deficiency (MCAD) - Medium-chain acyl-coenzyme A dehydrogenase
- Short-chain acyl-coenzyme A dehydrogenase deficiency (SCAD) - Short-chain acyl-coenzyme A dehydrogenase
- 3-hydroxyacyl-coenzyme A dehydrogenase deficiency (HADH) - 3-hydroxyacyl-coenzyme A dehydrogenase
Other Coenzyme A enzyme deficiencies
editCarnitine related
edit- Primary carnitine deficiency - SLC22A5 (carnitine transporter)
- Carnitine-acylcarnitine translocase deficiency - Carnitine-acylcarnitine translocase
- Carnitine palmitoyltransferase I deficiency (CPT) - Carnitine palmitoyltransferase I
- Carnitine palmitoyltransferase II deficiency (CPT) - Carnitine palmitoyltransferase II
