Invitae RCV000552459 SCV000625575 likely pathogenic Hereditary nonpolyposis colorectal neoplasms 2023-02-05 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 11 of the PMS2 gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in PMS2 are known to be pathogenic (PMID: 21376568, 24362816). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with PMS2-related conditions. ClinVar contains an entry for this variant (Variation ID: 455679). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
Ambry Genetics RCV002420350 SCV002719478 likely pathogenic Hereditary cancer-predisposing syndrome 2022-06-08 criteria provided, single submitter clinical testing The c.2006+1G>A intronic variant results from a G to A substitution one nucleotide after coding exon 11 of the PMS2 gene. This nucleotide position is highly conserved in available vertebrate species. In silico splice site analysis predicts that this alteration will weaken the native splice donor site. Alterations that disrupt the canonical splice site are expected to cause aberrant splicing, resulting in an abnormal protein or a transcript that is subject to nonsense-mediated mRNA decay. As such, this alteration is classified as likely pathogenic.
Myriad Genetics, Inc. RCV003449545 SCV004187653 likely pathogenic Lynch syndrome 4 2023-09-21 criteria provided, single submitter clinical testing This variant is considered likely pathogenic. This variant occurs within a consensus splice junction and is predicted to result in abnormal mRNA splicing of either an out-of-frame exon or an in-frame exon necessary for protein stability and/or normal function.
