RCV003541312 | SCV001409954 | uncertain significance | not provided | 2025-02-04 | criteria provided, single submitter | clinical testing | This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 1687 of the POLE protein (p.Ser1687Thr). This variant is present in population databases (no rsID available, gnomAD 0.01%). 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: 963205). 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%. RNA analysis performed to evaluate the impact of this missense change on mRNA splicing indicates it does not significantly alter splicing (internal data). 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 | RCV002339656 | SCV002643564 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-06-02 | criteria provided, single submitter | clinical testing | The p.S1687T variant (also known as c.5059T>A), located in coding exon 38 of the POLE gene, results from a T to A substitution at nucleotide position 5059. The serine at codon 1687 is replaced by threonine, an amino acid with similar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
