Description

This sequence change affects a donor splice site in intron 13 of the MSH2 gene. It is expected to disrupt RNA splicing and likely results in an absent or disrupted protein product. This variant is not present in population databases (ExAC no frequency). This variant has been reported in the literature in individuals with early onset colorectal cancer (PMID: 18307539, 17189986), and in families with Lynch syndrome or suspected Lynch syndrome (PMID: 24710284, 12362047). ClinVar contains an entry for this variant (Variation ID: 90921). Donor and acceptor splice site variants typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in MSH2 are known to be pathogenic (PMID: 15849733, 24362816). 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.
