not provided Uncertain:2
In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Observed in an individual with ovarian cancer (Song et al., 2021); This variant is associated with the following publications: (PMID: 22492711, 25801821, 32546565) -
This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 2268 of the POLE protein (p.Ser2268Leu). This variant is present in population databases (rs373791036, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with POLE-related conditions. ClinVar contains an entry for this variant (Variation ID: 405583). 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) indicates that this missense variant is not expected to disrupt POLE 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. -
not specified Uncertain:1
- -
Hereditary cancer-predisposing syndrome Benign: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. -
