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).
