Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jun 14, 2012 | The Gly1245Val variant in SOS1 has not been reported in the literature nor previ ously identified by our laboratory. Computational analyses (biochemical amino ac id properties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide stro ng support for or against an impact to the protein. In summary, additional infor mation is needed to fully assess the clinical significance of the Gly1245Val var iant. - |
SOS1-related disorder Uncertain:1
Uncertain significance, no assertion criteria provided | clinical testing | PreventionGenetics, part of Exact Sciences | Jun 04, 2024 | The SOS1 c.3734G>T variant is predicted to result in the amino acid substitution p.Gly1245Val. To our knowledge, this variant has not been reported in the literature or in gnomAD, indicating this variant is rare. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. - |
RASopathy Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Feb 21, 2023 | This sequence change replaces glycine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 1245 of the SOS1 protein (p.Gly1245Val). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with SOS1-related conditions. ClinVar contains an entry for this variant (Variation ID: 45369). 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) performed at Invitae indicates that this missense variant is not expected to disrupt SOS1 protein function. 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. - |
