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:Benign
Review Status:criteria provided, single submitter
Collection Method:clinical testing

This alteration is classified as benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.

Review Status:no assertion criteria provided
Collection Method:clinical testing

DNA sequence analysis of the EGFR gene demonstrated a sequence change, c.3467A>C, in exon 28 that results in an amino acid change, p.His1156Pro. This sequence change does not appear to have been previously described in individuals with EGFR-related disorders. This sequence change has been described in the gnomAD database with a frequency of 0.18% in the African subpopulation (dbSNP rs149174093). The p.His1156Pro change affects a poorly conserved amino acid residue located in a domain of the EGFR protein that is known to be functional. The p.His1156Pro substitution appears to be benign using several in-silico pathogenicity prediction tools (SIFT, PolyPhen2, Align GVGD, REVEL). Due to insufficient evidences and the lack of functional studies, the clinical significance of the p.His1156Pro change remains unknown at this time.
