Introduction
Long-chain fatty acid oxidation disorders (LC-FAOD) are a group of rare inborn errors of metabolism leading to serious consequences due to inability to convert long-chain fat into energy (1). LC-FAOD nuclear genes encode mitochondrial proteins necessary for energy production. There are 6 enzyme deficiencies associated with LC-FAOD.
Transport of fatty acids into cells and the fatty acid breakdown are necessary for energy production when sugar, or glucose, levels are low. Without this energy supply, people with LC-FAOD may have symptoms that include, but are not limited to muscle pain, muscle weakness, low blood sugar, and fatigue (2).
