• Fatty Acid Oxidation Disorders Diagnostic Testing Program

    MetaboSeq banner.

    The Cincinnati Children’s Molecular Genetics Laboratory introduces MetaboSeq, our next-generation sequencing panel of 19 genes associated with fatty acid oxidation disorders (FAOD).  

    MetaboSeq provides a rapid and cost-effective analysis of the most common genetic causes of nonspecific FAOD. The indications for MetaboSeq include: 

    • Abnormal newborn screen
    • Unexplained neonatal hypoglycemia
    • Recurrent maternal fatty liver of pregnancy
    • Reye syndrome
    • Rhabdomyolysis / skeletal myopathy
    • Cardiomyopathy or arrhythmias
    • Other nonspecific symptoms of FAOD, including:
      • Liver failure
      • Vomiting
      • Lethargy
      • Seizures
      • Coma

    Sanger sequencing of CPT2, ACADM, ACADVL and SLC22A5, as well as genotyping for the common E510Q mutation in HADHA, is also available when a specific diagnosis is suggested by preliminary biochemical testing.
