Genes affected
TSC2 (HGNC:12363): (TSC complex subunit 2) This gene is a tumor suppressor gene that encodes the growth inhibitory protein tuberin. Tuberin interacts with hamartin to form the TSC protein complex which functions in the control of cell growth. This TSC protein complex negatively regulates mammalian target of rapamycin complex 1 (mTORC1) signaling which is a major regulator of anabolic cell growth. Mutations in this gene have been associated with tuberous sclerosis and lymphangioleiomyomatosis. [provided by RefSeq, May 2022]

Submissions by phenotype
Tuberous sclerosis syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | All of Us Research Program, National Institutes of Health | Jan 08, 2024 | This variant causes a C to A nucleotide substitution at the -14 position of intron 15 of the TSC2 gene. To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with tuberous sclerosis complex in the literature. This variant has been identified in 2/280996 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. - |
not specified Benign:1
Likely benign, criteria provided, single submitter | clinical testing | GeneDx | Jul 06, 2015 | This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. - |
Tuberous sclerosis 2 Benign:1
