Ambry Genetics | RCV002447637 | SCV002680815 | pathogenic | Hereditary cancer-predisposing syndrome | 2022-03-04 | criteria provided, single submitter | clinical testing | The c.848_849delCT pathogenic mutation, located in coding exon 6 of the POT1 gene, results from a deletion of two nucleotides at nucleotide positions 848 to 849, causing a translational frameshift with a predicted alternate stop codon (p.S283*). This alteration is expected to result in loss of function by premature protein truncation or nonsense-mediated mRNA decay. As such, this alteration is interpreted as a disease-causing mutation. |

RCV003746629 | SCV004512559 | pathogenic | Tumor predisposition syndrome 3 | 2023-07-20 | criteria provided, single submitter | clinical testing | This variant is not present in population databases (gnomAD no frequency). This sequence change creates a premature translational stop signal (p.Ser283*) in the POT1 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in POT1 are known to be pathogenic (PMID: 32155570). This variant has not been reported in the literature in individuals affected with POT1-related conditions. For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1763542). |
