The S245L missense variant in the ACADM gene has been reported previously in a patient who was homozygous for the S245L variant and who was detected by newborn screening for medium chain acyl-CoA dehydrogenase (MCAD) deficiency. This patient had enzyme studies that showed residual MCAD activity between classical" MCAD deficiency and heterozygous carriers of MCAD deficiency (Zschocke et al., 2001). This variant has also been described in another patient who was compound heterozygous for S245L and another variant; this individual was reported to have significantly higher residual MCAD enzyme activity (Touw et al., 2013). The S245L variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other 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. Therefore, this variant is likely pathogenic; however, the possibility that it is benign cannot be excluded."
