Of the total sample, 50% (nine) had FAODs, distributed as follows: four cases of MCAD, one with long-chain acyl-CoA dehydrogenase (LCAD) deficiency, one with carnitine-acylcarnitine translocase (CACT) deficiency, two with carnitine palmitoyltransferase II (CPT II) deficiency, and one with multiple acyl-CoA dehydrogenase (MADD) deficiency. This evidence concerns the gene SLC25A20 and medium chain acyl-CoA dehydrogenase deficiency.
