Invitae RCV000229589 SCV000285277 pathogenic Tuberous sclerosis 2 2016-01-11 criteria provided, single submitter clinical testing This sequence change affects an acceptor splice site in intron 19. It is expected to disrupt mRNA splicing and likely results in an absent or disrupted protein product. This variant has been reported in the literature in individuals affected with a TSC2-related disease (PMID: 11520734, 17304050), and has been reported in individuals in the Leiden Open-source Variation Database (PMID: 21520333). In summary, donor and acceptor splice site variants are typically truncating (PMID: 16199547), and truncating variants in TSC2 are known to be pathogenic (PMID: 10205261, 17304050). For these reasons, this variant has been classified as Pathogenic.
GeneDx RCV000482722 SCV000567134 pathogenic not provided 2015-07-14 criteria provided, single submitter clinical testing The c.2098-1 G>A splice site variant in the TSC2 gene has been previously reportedmultiple times in association with tuberous sclerosis complex (TSC) (Dabora et al., 2001;Au et al., 2007; TSC2 LOVD). This variant destroys the canonical splice acceptor site in intron 19, and is expected to cause abnormal gene splicing. Therefore, we interpret the c.2098-1 variant in TSC2 as pathogenic.
