| Invitae | RCV000476212 | SCV000547669 | uncertain significance | Colorectal cancer, susceptibility to, 10 | 2024-01-16 | criteria provided, single submitter | clinical testing | This sequence change replaces valine, which is neutral and non-polar, with methionine, which is neutral and non-polar, at codon 1025 of the POLD1 protein (p.Val1025Met). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with POLD1-related conditions. ClinVar contains an entry for this variant (Variation ID: 408116). 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 POLD1 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 | RCV002319502 | SCV002606838 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-07-12 | criteria provided, single submitter | clinical testing | The p.V1025M variant (also known as c.3073G>A), located in coding exon 24 of the POLD1 gene, results from a G to A substitution at nucleotide position 3073. The valine at codon 1025 is replaced by methionine, an amino acid with highly similar 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. |
