RCV000524125 | SCV000551072 | pathogenic | Hereditary nonpolyposis colorectal neoplasms | 2023-11-28 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Leu634*) in the MSH6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MSH6 are known to be pathogenic (PMID: 18269114, 24362816). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with endometrial cancer and other Lynch syndrome-associated cancers (PMID: 12732731, 15098177). ClinVar contains an entry for this variant (Variation ID: 89232). For these reasons, this variant has been classified as Pathogenic. |
| Ambry Genetics | RCV001013617 | SCV001174225 | pathogenic | Hereditary cancer-predisposing syndrome | 2024-02-01 | criteria provided, single submitter | clinical testing | The c.1901_1902delTG pathogenic mutation, located in coding exon 4 of the MSH6 gene, results from a deletion of two nucleotides at nucleotide positions 1901 to 1902, causing a translational frameshift with a predicted alternate stop codon (p.L634*). This mutation has been reported in a proband with MSI-high endometrial cancer diagnosed at age 58 (Goodfellow PJ et al. Proc. Natl. Acad. Sci. U.S.A., 2003 May;100:5908-13). In addition to the clinical data presented in the literature, 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. |
| Quest Diagnostics Nichols Institute San Juan Capistrano | RCV001284179 | SCV001469820 | pathogenic | not provided | 2020-01-03 | criteria provided, single submitter | clinical testing | The variant creates a premature stop codon, and is therefore predicted to result in the loss of a functional protein. Found in at least one patient with expected phenotype for this gene, and not found in general population data. Segregation with disease in affected individuals from a single family. |
