| Ambry Genetics | RCV000562180 | SCV000671558 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-12-28 | criteria provided, single submitter | clinical testing | The p.M294I variant (also known as c.882G>A), located in coding exon 9 of the POLE gene, results from a G to A substitution at nucleotide position 882. The methionine at codon 294 is replaced by isoleucine, an amino acid with highly similar properties. This amino acid position is highly conserved in available vertebrate species. 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. |

RCV001575808 | SCV000823624 | uncertain significance | not provided | 2025-01-30 | criteria provided, single submitter | clinical testing | This sequence change replaces methionine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 294 of the POLE protein (p.Met294Ile). This variant is present in population databases (rs774328855, gnomAD 0.002%). 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: 484499). 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. |
