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).

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.R962C variant (also known as c.2884C>T), located in coding exon 24 of the EGFR gene, results from a C to T substitution at nucleotide position 2884. The arginine at codon 962 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 962 of the EGFR protein (p.Arg962Cys). This variant is present in population databases (rs17337451, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with EGFR-related conditions. ClinVar contains an entry for this variant (Variation ID: 855873). 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) has been performed for this missense variant. However, the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on EGFR protein function. 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.

Significance:Uncertain significance

Review Status:no assertion criteria provided

Collection Method:clinical testing

The EGFR c.2884C>T variant is predicted to result in the amino acid substitution p.Arg962Cys. This variant was reported in several individuals with kidney cancer in childhood or prostate cancer (Kim et al. 2021. PubMed ID: 34308104; Johnson AM et al. 2014. PubMed ID: 25111073). This variant is reported in 0.014% of alleles in individuals of European (Non-Finnish) descent in gnomAD. This variant is interpreted as uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/855873/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
