Very Long-Chain Acyl-CoA Dehydrogenase Deficiency (ACADVL) Sequencing and Deletion/Duplication

Ordering Recommendation

Preferred molecular test to diagnose or rule out very long-chain acyl-CoA dehydrogenase (VLCAD) deficiency following clinical and/or biochemical presentation. May also be used for carrier testing for the reproductive partner of an individual who is affected with or is a carrier of VLCAD deficiency. Also refer to Acylcarnitine Quantitative Profile, Plasma (0040033), Carnitine Panel (0081110), and Organic Acids, Urine (0098389).
