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 glycine, which is neutral and non-polar, with aspartic acid, which is acidic and polar, at codon 428 of the EGFR protein (p.Gly428Asp). This variant is present in population databases (rs606231253, gnomAD no frequency). This missense change has been observed in individuals with neonatal inflammatory skin and bowel disease (PMID: 24691054, 26436111, 32602142). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 157499). 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: 24691054, 26436111). For these reasons, this variant has been classified as Pathogenic. -
