Invitae | RCV003656752 | SCV001414876 | uncertain significance | not provided | 2023-12-15 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 2225 of the POLE protein (p.Arg2225Gly). This variant is present in population databases (rs765125852, gnomAD 0.03%). 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: 967015). 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 | RCV002366067 | SCV002661766 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-07-11 | criteria provided, single submitter | clinical testing | The p.R2225G variant (also known as c.6673C>G), located in coding exon 48 of the POLE gene, results from a C to G substitution at nucleotide position 6673. The arginine at codon 2225 is replaced by glycine, 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. |
