The R2967S variant in the SACS gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The R2967S variant was not observed in approximately 6500 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 R2967S variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species, however, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Therefore, we interpret R2967S as a variant of uncertain significance.
