RCV003238834 | SCV001223048 | uncertain significance | not provided | 2024-08-07 | criteria provided, single submitter | clinical testing | This sequence change replaces tyrosine, which is neutral and polar, with cysteine, which is neutral and slightly polar, at codon 84 of the POLE protein (p.Tyr84Cys). 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: 853626). 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 | RCV002429676 | SCV002741637 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-12-21 | criteria provided, single submitter | clinical testing | The p.Y84C variant (also known as c.251A>G), located in coding exon 3 of the POLE gene, results from an A to G substitution at nucleotide position 251. The tyrosine at codon 84 is replaced by cysteine, an amino acid with highly 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. |
