The R366Q variant in the OPA1 gene has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The R366Q 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 R366Q 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 within the Dynamin-type G domain that is conserved across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret R366Q as a likely pathogenic variant; however, the possibility that this is a rare benign variant cannot be completely excluded.
