Disorders affecting the oxidation of long-chain fatty acids are complex, potentially life-threatening, metabolic conditions. A number of genetically distinct conditions exist, depending on the gene and protein affected, but there are some common clinical and biochemical features. Newborn screening, which allows early intervention to prevent long-term morbidity, is not universally available. Even with screening, it is important that health professionals recognize the symptoms that may manif...

Long-chain fatty acid oxidation disorders (LC-FAODs) are rare, inherited conditions. With an LC-FAOD, the body has trouble breaking down fat for energy, which can lead to symptoms such as low blood sugars, muscle pain/weakness, and heart problems. LC-FAODs are diagnosed by newborn screening or symptoms later in life. Management includes a specialized nutrition plan, and prevention of fasting, especially during illness.
