Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BP4_Strong
The ENST00000320574.10(POLE):c.3740C>T(p.Pro1247Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000291 in 1,614,188 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 (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. P1247S) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 22, 2024 | This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 1247 of the POLE protein (p.Pro1247Leu). This variant is present in population databases (rs572986717, gnomAD 0.02%). 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: 405683). 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 | St. Jude Molecular Pathology, St. Jude Children's Research Hospital | Aug 31, 2022 | The POLE c.3740C>T (p.Pro1247Leu) missense change has a maximum subpopulation frequency of 0.025% in gnomAD v2.1.1 (https://gnomad.broadinstitute.org). The in silico tool REVEL predicts a benign effect on protein function, but to our knowledge this prediction has not been confirmed by functional studies. To our knowledge, this variant has not been reported in individuals with POLE-associated polyposis, FILS syndrome, or IMAGE-I syndrome. In summary, the evidence currently available is insufficient to determine the clinical significance of this variant. It has therefore been classified as of uncertain significance. - |
