Submissions by phenotype
Hereditary cancer-predisposing syndrome Uncertain:1Benign:1
This alteration is classified as likely 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. -

EGFR-related lung cancer Uncertain:1
This sequence change replaces arginine, which is basic and polar, with histidine, which is basic and polar, at codon 831 of the EGFR protein (p.Arg831His). This variant is present in population databases (rs150036236, gnomAD 0.02%). This missense change has been observed in individual(s) with lung cancer or prostate cancer or isolated hypogonadotropic hypogonadism (PMID: 30098700, 30610926, 31721094, 32978518). ClinVar contains an entry for this variant (Variation ID: 560007). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies are conflicting or provide insufficient evidence to determine the effect of this variant on EGFR function (PMID: 20942962, 25382819, 27294619, 32978518). 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. -
