Tuberous sclerosis complex (TSC) is an autosomal dominant disease characterized by systemic hamartomas. Two genes, TSCI and TSCII, which encode hamartin and tuberin, are responsible for TSC. The complex of hamartin and tuberin inhibits the mammalian target of rapamycin (mTOR),1 which has numerous functions in the regulation of protein synthesis and cell growth. The constitutive activation of mTOR is associated with abnormal cellular proliferation, which causes TSC-related hamartomas.
