Labcorp Genetics (formerly Invitae), Labcorp RCV001797714 SCV004296674 pathogenic Tuberous sclerosis 2 2024-10-30 criteria provided, single submitter clinical testing This sequence change affects a donor splice site in intron 34 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). This variant is not present in population databases (gnomAD no frequency). Disruption of this splice site has been observed in individual(s) with tuberous sclerosis complex (PMID: 25782670). ClinVar contains an entry for this variant (Variation ID: 373118). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic.
