MADD is known to be caused by variants in ETFA, ETFB, and ETFDH, though in recent years the riboflavin transporter genes and mitochondrial FAD transporter gene have also been associated with MADD‐like phenotype (Bosch et al., 2011; Schiff et al., 2016). The gene discussed is SLC25A32; the disease is multiple acyl-CoA dehydrogenase deficiency.
