Electron transfer flavoprotein (ETF) genes (ETFA and ETFB), some riboflavin transporter genes (SLC52A1, SLC52A2, SLC52A3, and SLC25A32), and FAD synthase gene (FLAD1) were also reported as the causative genes for late-onset MADD [3, 4]. The gene discussed is FLAD1; the disease is multiple acyl-CoA dehydrogenase deficiency.
