Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM1PM2
The NM_005228.5(EGFR):āc.2270A>Gā(p.Lys757Arg) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000616 in 1,461,622 control chromosomes in the GnomAD database, with no homozygous occurrence. Variant has been reported in ClinVar as Uncertain significance (ā ). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K757M) has been classified as Uncertain significance.

EGFR-related lung cancer Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Dec 26, 2023 | This sequence change replaces lysine, which is basic and polar, with arginine, which is basic and polar, at codon 757 of the EGFR protein (p.Lys757Arg). This variant is present in population databases (rs397517102, gnomAD 0.03%). This missense change has been observed in individual(s) with lung cancer (PMID: 30610926). ClinVar contains an entry for this variant (Variation ID: 560009). 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 not expected to disrupt EGFR protein function with a negative 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. - |
