The G98S variant in the TUBB3 gene has been reported previously as a de novo change in a child with congenital fibrosis of the extraocular muscles and structural abnormalities of the brain (Whitman et al., 2015). The G98S 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 G98S 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. We interpret G98S as a pathogenic variant.
