Inborn error of lipid metabolism Classification and external resources
Several fatty acid moleculesICD-10 E75, E78 ICD-9 272, 277.85 MeSH D008052 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:
Contents
Coenzyme A dehydrogenase deficiencies
- 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
