The R366H missense variant has been reported previously in association with very long chain acyl-CoA dehydrogenase (VLCAD) deficiency in several unrelated individuals who were homozygous for R366H, or heterozygous for R366H and another pathogenic variant in the ACADVL gene (Antunes et al., 2013; Andresen et al., 1999; Gobin-Limballe et al., 2010; Evans et al., 2016). The R366H variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved across species, and in silico analysis predicts this variant is probably damaging to the protein structure/function. A missense variant in the same residue (R366C) and a nearby residue (Q368P) have been reported in the Human Gene Mutation Database in association with VLCAD deficiency (Stenson et al., 2014), supporting the functional importance of this region of the protein. Therefore we interpret R366H to be a pathogenic variant.
