GeneDx RCV000433930 SCV000535786 uncertain significance not provided 2017-01-19 criteria provided, single submitter clinical testing The R391W variant in the SPG7 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R391W variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The R391W 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. We interpret R391W as a variant of uncertain significance.
