Variant summary

Our verdict is Likely benign. The variant received -4 ACMG points: 0P and 4B. BS1

The NM_005228.5(EGFR):​c.88+1215_88+1228delACACACACACACAC variant causes a intron change involving the alteration of a non-conserved nucleotide. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

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).

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• BS1: Variant frequency is greater than expected in population eas. GnomAd4 allele frequency = 0.000179 (26/145242) while in subpopulation EAS AF = 0.00308 (15/4866). AF 95% confidence interval is 0.0019. There are 0 homozygotes in GnomAd4. There are 18 alleles in the male GnomAd4 subpopulation. Median coverage is 0. This position passed quality control check.
