| Invitae | RCV001054272 | SCV001218577 | likely pathogenic | Hereditary nonpolyposis colorectal neoplasms | 2023-06-21 | criteria provided, single submitter | clinical testing | 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. Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. ClinVar contains an entry for this variant (Variation ID: 89974). Disruption of this splice site has been observed in individual(s) with clinical features of MLH1-related conditions (PMID: 21520333). This variant is not present in population databases (gnomAD no frequency). This sequence change affects a donor splice site in intron 17 of the MLH1 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 MLH1 are known to be pathogenic (PMID: 15713769, 24362816). |

RCV003451090 | SCV004185705 | likely pathogenic | Colorectal cancer, hereditary nonpolyposis, type 2 | 2023-07-25 | 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. |
