Genes affected

EGFR (HGNC:3236): (epidermal growth factor receptor) The protein encoded by this gene is a transmembrane glycoprotein that is a member of the protein kinase superfamily. This protein is a receptor for members of the epidermal growth factor family. EGFR is a cell surface protein that binds to epidermal growth factor, thus inducing receptor dimerization and tyrosine autophosphorylation leading to cell proliferation. Mutations in this gene are associated with lung cancer. EGFR is a component of the cytokine storm which contributes to a severe form of Coronavirus Disease 2019 (COVID-19) resulting from infection with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).

This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 769 of the EGFR protein (p.Val769Met). This variant is present in population databases (rs147149347, gnomAD 0.02%). This missense change has been observed in individual(s) with lung cancer (PMID: 32913967). ClinVar contains an entry for this variant (Variation ID: 208821). 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 EGFR protein function with a negative predictive value of 80%. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on EGFR function (PMID: 32913967). 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. -
