Invitae RCV001853086 SCV002266850 likely pathogenic Tuberous sclerosis 2 2021-03-24 criteria provided, single submitter clinical testing This sequence change affects an acceptor splice site in intron 17 of the TSC2 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 TSC2 are known to be pathogenic (PMID: 10205261, 17304050). 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. Disruption of this splice site has been observed in individual(s) with tuberous sclerosis (PMID: 16981987). ClinVar contains an entry for this variant (Variation ID: 64895). This variant is not present in population databases (ExAC no frequency).
