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 arginine, which is basic and polar, with histidine, which is basic and polar, at codon 831 of the EGFR protein (p.Arg831His). This variant is present in population databases (rs150036236, gnomAD 0.02%). This missense change has been observed in individual(s) with lung cancer or prostate cancer or isolated hypogonadotropic hypogonadism (PMID: 30098700, 30610926, 31721094, 32978518). ClinVar contains an entry for this variant (Variation ID: 560007). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on EGFR function (PMID: 20942962, 25382819, 27294619, 32978518). 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. -
