RCV001366717 | SCV001563030 | uncertain significance | EGFR-related lung cancer | 2024-09-03 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 796 of the EGFR protein (p.Gly796Ser). This variant is present in population databases (rs754426793, gnomAD 0.01%). This missense change has been observed in individual(s) with squamous cell carcinoma of the head and neck (PMID: 18528899). ClinVar contains an entry for this variant (Variation ID: 1057685). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt EGFR protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects EGFR function (PMID: 18193092). 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. |

Quest Diagnostics Nichols Institute San Juan Capistrano | RCV001531041 | SCV004221885 | uncertain significance | not provided | 2023-06-30 | criteria provided, single submitter | clinical testing | In the published literature, this variant has been reported in individuals with squamous cell carcinoma of the head and neck (PMID: 18528899 (2008)). In vitro expression of this variant results in increased cell proliferation, invasion and EGFR downstream signaling associated with cancer progression (PMID: 18193092 (2008)). The frequency of this variant in the general population, 0.000012 (3/251474 chromosomes (Genome Aggregation Database, http://gnomad.broadinstitute.org)), is uninformative in the assessment of its pathogenicity. Analysis of this variant using bioinformatics tools for the prediction of the effect of amino acid changes on protein structure and function yielded predictions that this variant is damaging. Additional analysis using software algorithms for the prediction of the effect of nucleotide changes on EGFR mRNA splicing yielded predictions that this variant may result in the gain of a cryptic splice site without affecting the natural splice sites . Based on the available information, we are unable to determine the clinical significance of this variant. |
