| Invitae | RCV003656227 | SCV001206502 | uncertain significance | not provided | 2023-12-03 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with tryptophan, which is neutral and slightly polar, at codon 847 of the POLE protein (p.Arg847Trp). 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: 840730). 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 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 | RCV003160293 | SCV003892189 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-03-05 | criteria provided, single submitter | clinical testing | The p.R847W variant (also known as c.2539C>T), located in coding exon 22 of the POLE gene, results from a C to T substitution at nucleotide position 2539. The arginine at codon 847 is replaced by tryptophan, an amino acid with dissimilar 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. |
