Invitae | RCV000823303 | SCV000964157 | uncertain significance | Colorectal cancer, susceptibility to, 10 | 2022-08-09 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 665093). This variant has not been reported in the literature in individuals affected with POLD1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces histidine, which is basic and polar, with arginine, which is basic and polar, at codon 298 of the POLD1 protein (p.His298Arg). |
Ambry Genetics | RCV002372359 | SCV002683623 | uncertain significance | Hereditary cancer-predisposing syndrome | 2021-08-11 | criteria provided, single submitter | clinical testing | The p.H298R variant (also known as c.893A>G), located in coding exon 7 of the POLD1 gene, results from an A to G substitution at nucleotide position 893. The histidine at codon 298 is replaced by arginine, 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. |
