Labcorp Genetics (formerly Invitae), Labcorp RCV001568888 SCV000544170 uncertain significance not provided 2025-01-06 criteria provided, single submitter clinical testing This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 1426 of the POLE protein (p.Val1426Ile). This variant is present in population databases (rs775072147, gnomAD 0.03%). This missense change has been observed in individual(s) with POLE-related conditions (PMID: 32522261). ClinVar contains an entry for this variant (Variation ID: 405845). 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.

Ambry Genetics RCV004943866 SCV005481523 likely benign Hereditary cancer-predisposing syndrome 2024-08-23 criteria provided, single submitter clinical testing 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.
