Invitae | RCV003541152 | SCV001385221 | uncertain significance | not provided | 2023-12-07 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with glutamic acid, which is acidic and polar, at codon 2133 of the POLE protein (p.Val2133Glu). This variant is present in population databases (no rsID available, gnomAD 0.0009%). 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: 943403). 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. |
Ambry Genetics | RCV003163627 | SCV003911797 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-01-18 | criteria provided, single submitter | clinical testing | The p.V2133E variant (also known as c.6398T>A), located in coding exon 46 of the POLE gene, results from a T to A substitution at nucleotide position 6398. The valine at codon 2133 is replaced by glutamic acid, an amino acid with dissimilar 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. |
