Labcorp Genetics (formerly Invitae), Labcorp RCV003628119 SCV004429268 pathogenic Tuberous sclerosis 2 2023-01-05 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. This variant disrupts a region of the TSC2 protein in which other variant(s) (p.Arg1743Gln) have been determined to be pathogenic (PMID: 10732801, 16114042, 18854862, 20165957, 21309039). This suggests that this is a clinically significant region of the protein, and that variants that disrupt it are likely to be disease-causing. This variant has not been reported in the literature in individuals affected with TSC2-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change results in a frameshift in the TSC2 gene (p.Ile1735Thrfs*90). While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 73 amino acid(s) of the TSC2 protein and extend the protein by 16 additional amino acid residues.
