Invitae | RCV000466428 | SCV000547673 | uncertain significance | Colorectal cancer, susceptibility to, 10 | 2024-01-17 | criteria provided, single submitter | clinical testing | This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1053 of the POLD1 protein (p.Arg1053Cys). 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 missense change has been observed in individual(s) with breast cancer (PMID: 35264596). ClinVar contains an entry for this variant (Variation ID: 408119). 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. |

RCV003960027 | SCV004769438 | uncertain significance | POLD1-related condition | 2023-11-13 | criteria provided, single submitter | clinical testing | The POLD1 c.3157C>T variant is predicted to result in the amino acid substitution p.Arg1053Cys. This variant has been reported in an individual with breast cancer (Table S3, Guindalini et al. 2022. PubMed ID: 35264596). This variant is reported in 0.0056% of alleles in individuals of East Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/19-50920465-C-T). It is interpreted as a variant of uncertain significance in ClinVar (https://www.ncbi.nlm.nih.gov/clinvar/variation/408119/). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
