Invitae | RCV000703205 | SCV000832094 | uncertain significance | Colorectal cancer, susceptibility to, 10 | 2023-06-09 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with glycine, which is neutral and non-polar, at codon 322 of the POLD1 protein (p.Arg322Gly). This variant has not been reported in the literature in individuals affected with POLD1-related conditions. 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. 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 POLD1 protein function. ClinVar contains an entry for this variant (Variation ID: 579828). |
Ambry Genetics | RCV002369944 | SCV002689055 | uncertain significance | Hereditary cancer-predisposing syndrome | 2023-08-04 | criteria provided, single submitter | clinical testing | The p.R322G variant (also known as c.964C>G), located in coding exon 7 of the POLD1 gene, results from a C to G substitution at nucleotide position 964. The arginine at codon 322 is replaced by glycine, an amino acid with dissimilar properties. This amino acid position is well conserved in available vertebrate species. 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. |
