Invitae | RCV000817038 | SCV000957574 | uncertain significance | Tumor predisposition syndrome 3 | 2023-08-28 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with POT1-related conditions. ClinVar contains an entry for this variant (Variation ID: 659943). 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 POT1 protein function. 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. This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 272 of the POT1 protein (p.Gly272Ser). |
Ambry Genetics | RCV001027221 | SCV001189739 | uncertain significance | Hereditary cancer-predisposing syndrome | 2022-10-31 | criteria provided, single submitter | clinical testing | The p.G272S variant (also known as c.814G>A), located in coding exon 6 of the POT1 gene, results from a G to A substitution at nucleotide position 814. The glycine at codon 272 is replaced by serine, an amino acid with similar properties. This amino acid position is highly 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. |
