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 962 of the EGFR protein (p.Arg962His). This variant is present in population databases (rs144496976, gnomAD 0.07%), including at least one homozygous and/or hemizygous individual. This missense change has been observed in individual(s) with breast cancer, osteosarcoma, non-Hodgkin lymphoma, and nodular sclerosis Hodgkin lymphoma (PMID: 32191290, 34308104, 35264596). ClinVar contains an entry for this variant (Variation ID: 134027). 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 expected to disrupt EGFR protein function with a positive predictive value of 80%. 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. -

The EGFR c.2885G>A variant is predicted to result in the amino acid substitution p.Arg962His. This variant has been reported in multiple individuals with breast cancer, osteosarcoma, and diffuse large B cell lymphoma (see for example, Table S3, Guindalini et al. 2022. PubMed ID: 35264596; Table S5, Mirabello et al. 2020. PubMed ID: 32191290; search 55268045 in Table S2, Kim et al. 2021. PubMed ID: 34308104). This variant is reported in 0.065% of alleles in individuals of South Asian descent in gnomAD. This variant has been classified as a variant of uncertain significance by other institutions in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/134027/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
