Confirmatory genetic testing may be appropriate for anyone with a suspected LC-FAOD diagnosis1
DIAGNOSING LC-FAOD
LC-FAOD is rare; there are only an estimated 100 births per year with a confirmed diagnosis in the United States. An estimated 2,000 to 3,500 patients in the United States are currently living with LC-FAOD.2*
Onset of LC-FAOD symptoms typically occurs during the neonatal period and infancy. However, some patients with slower disease progression may NOT be diagnosed or diagnosed at a later age.3,4
Confirmatory genetic testing may be appropriate for anyone with a suspected LC-FAOD diagnosis based on clinical symptoms, laboratory findings, or a combination of both.1
Screening of genes involved in LC-FAOD—ACADVL, CPT1A, CPT2, HADHA, HADHB, and SLC25A20—are commercially available. Certain LC-FAOD types may require additional mutational analysis.5
*LC-FAOD is a rare disease with limited epidemiological data; therefore, estimates provided here are based on internal data and market research.
