Revision as of 17:31, 10 December 2014

Tuberous sclerosis, also tuberous sclerosis complex (abbreviated TSC), is an autosomal dominant syndrome associated with an increased risk of hamartomas and some risk increase for malignant tumours.

Historically described as:[1]

  1. Epilepsy.
  2. Mental retardation.
  3. Adenoma sebaceum (angiofibromas).

General

  • Autosomal dominant with variable penetrance.[2]
  • Majority (60-70%) are de novo mutations.[2]

Associations

Pathologic:

Note:

  • The same genes (TSC1, TSC2) are implicated in PEComas.

Mnemonic SALSA HEART:[5]

Genes

  • TSC1.[7]
  • TSC2.[8]
    • Some evidence to suggest it is more often implicated in malignant tumours (than TSC1).[9]
    • TSC2 mutations have a higher prevalence (than TSC1 mutations) and are considered more aggressive.[3]

Incidence

~1 in 10,000 population.[1][9]
