GeneDx RCV000498965 SCV000589302 uncertain significance not provided 2017-06-29 criteria provided, single submitter clinical testing The G221R variant has been reported in an individual with biochemical findings consistent with medium chain acyl-CoA dehydrogenase (MCAD) deficiency who also harbored another variant in the ACADM gene, although it was not determined if the variants were in cis or trans (Smith et al., 2010). The G221R variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The G221R 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. In silico analysis predicts this variant is probably damaging to the protein structure/function. In summary, based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
