RCV000414721 | SCV000491468 | uncertain significance | not specified | 2016-03-03 | criteria provided, single submitter | clinical testing | The D705Y variant in the SOS1 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The D705Y 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 D705Y 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 D705Y as a variant of uncertain significance |

RCV003754876 | SCV004554673 | uncertain significance | Noonan syndrome 9 | 2023-06-17 | criteria provided, single submitter | clinical testing | In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on SOS2 protein function. ClinVar contains an entry for this variant (Variation ID: 372928). This variant has not been reported in the literature in individuals affected with SOS2-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.0009%). This sequence change replaces aspartic acid, which is acidic and polar, with tyrosine, which is neutral and polar, at codon 705 of the SOS2 protein (p.Asp705Tyr). |
