Labcorp Genetics (formerly Invitae), Labcorp RCV001039043 SCV001202550 pathogenic Hereditary nonpolyposis colorectal neoplasms 2020-01-31 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This sequence change creates a premature translational stop signal (p.Cys783*) in the MSH6 gene. It is expected to result in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has not been reported in the literature in individuals with MSH6-related conditions. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Loss-of-function variants in MSH6 are known to be pathogenic (PMID: 18269114, 24362816).
Myriad Genetics, Inc. RCV003455163 SCV004187359 pathogenic Lynch syndrome 5 2023-08-17 criteria provided, single submitter clinical testing This variant is considered pathogenic. This variant creates a termination codon and is predicted to result in premature protein truncation.
