TSC1 (tuberous sclerosis 1) is a gene that encodes for a protein, hamartin, that interacts with a protein encoded by the TSC2 gene, tuberin (Genetics Home Reference 2013). TSC1 acts as a tumor suppressor, through regulation of the mTOR pathway, which is involved in cell proliferation (Genetics Home Reference 2013PMID: 21533174). Mutations in TSC1 are observed in bladder cancer (COSMIC; PMID: 22923433PMID: 21533174).

TSC1 is altered in 1.80% of all cancers with bladder urothelial carcinoma, lung adenocarcinoma, colon adenocarcinoma, endometrial endometrioid adenocarcinoma, and breast invasive ductal carcinoma having the greatest prevalence of alterations [3].

TSC1 GENIE Cases - Top Diseases

The most common alterations in TSC1 are TSC1 Mutation (2.09%), TSC1 Mutation (somatic) (2.09%), TSC1 Loss (0.06%), TSC1 R420Gfs*20 (0.03%), and TSC1 N891Kfs*13 (0.03%) [3].
