RCV001766708 | SCV000955069 | uncertain significance | not provided | 2025-01-21 | criteria provided, single submitter | clinical testing | This sequence change replaces proline, which is neutral and non-polar, with alanine, which is neutral and non-polar, at codon 1157 of the POLE protein (p.Pro1157Ala). This variant is not present in population databases (gnomAD no frequency). 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: 657938). 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 expected to disrupt POLE protein function with a positive 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 | RCV002453848 | SCV002612982 | uncertain significance | Hereditary cancer-predisposing syndrome | 2024-04-30 | criteria provided, single submitter | clinical testing | The p.P1157A variant (also known as c.3469C>G), located in coding exon 29 of the POLE gene, results from a C to G substitution at nucleotide position 3469. The proline at codon 1157 is replaced by alanine, an amino acid with highly 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. |
