Variant summary
Our verdict is Likely benign. Variant got -2 ACMG points: 0P and 2B. BP4_Moderate
The ENST00000320574.10(POLE):c.3745G>A(p.Val1249Met) variant causes a missense change. The variant allele was found at a frequency of 0.000013 in 1,461,876 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. V1249V) has been classified as Likely benign.

Submissions by phenotype
not provided Uncertain:3
Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 25, 2024 | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1249 of the POLE protein (p.Val1249Met). This variant is present in population databases (rs762626359, gnomAD 0.004%). 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: 405830). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae 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. - |

Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jan 20, 2023 | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge - |
Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Dec 14, 2021 | The p.V1249M variant (also known as c.3745G>A), located in coding exon 30 of the POLE gene, results from a G to A substitution at nucleotide position 3745. The valine at codon 1249 is replaced by methionine, an amino acid with highly similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |

not provided, no classification provided | phenotyping only | GenomeConnect - Invitae Patient Insights Network | - | Variant interpreted as Uncertain significance and reported on 12-07-2018 by Invitae. GenomeConnect-Invitae Patient Insights Network assertions are reported exactly as they appear on the patient-provided report from the testing laboratory. Registry team members make no attempt to reinterpret the clinical significance of the variant. Phenotypic details are available under supporting information. - |
