| Invitae | RCV001064448 | SCV001229351 | pathogenic | Hereditary nonpolyposis colorectal neoplasms | 2019-02-19 | criteria provided, single submitter | clinical testing | This variant has not been reported in the literature in individuals with MSH6-related conditions. For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in MSH6 are known to be pathogenic (PMID: 18269114, 24362816). This variant is not present in population databases (ExAC no frequency). This sequence change creates a premature translational stop signal (p.Met868Serfs*5) in the MSH6 gene. It is expected to result in an absent or disrupted protein product. |
| Ambry Genetics | RCV003160528 | SCV003865239 | pathogenic | Hereditary cancer-predisposing syndrome | 2022-12-22 | criteria provided, single submitter | clinical testing | The c.2603delT pathogenic mutation, located in coding exon 4 of the MSH6 gene, results from a deletion of one nucleotide at nucleotide position 2603, causing a translational frameshift with a predicted alternate stop codon (p.M868Sfs*5). This variant is considered to be rare based on population cohorts in the Genome Aggregation Database (gnomAD). 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. |
