ACADVL and multiple acyl-CoA dehydrogenase deficiency: In addition, maternal vitamin B2 deficiency could lead to acylcarnitine and organic acid profiles like those observed in multiple acyl-CoA dehydrogenase deficiency (MIM #231680; ETFA, *608053; ETFB *130410; ETFDH, *231675) or very long chain acyl-CoA dehydrogenase (ACADVL, MIM *609575 #201475) [10].
