Genetics features

  • The TSC genes are growth suppressor genes
  • The TSC 1 gene is on chromosome 9: its product is harmatin
  • The TSC 2 gene is on chromosome 16: its product is tuberin
  • TSC2 gene mutations are associated with a worse phenotype
  • The transmission of the mutations is autosomal dominant
  • There is no family history in 66% of cases: these are de novo mutations
