Definition / general
Terminology
  • TSC2 / PKD1 contiguous gene syndrome: both kidneys are enlarged and cystic, have classic angiomyolipomas and rare intraglomerular microlesions (Am J Surg Pathol 2002;26:198)
Etiology
  • Caused by alterations of TSC1 gene (9q34, encodes hamartin) and TSC2 gene (16p13.3, encodes tuberin, which interacts with hamartin)
Clinical features
  • Patients suffer intellectual disability and infantile / childhood seizures
  • 60 - 70% of tuberous sclerosis cases are sporadic (OMIM - 191100)
  • Patients with tuberous sclerosis present at younger age, tumors are usually larger and more often bilateral (Urology 2008;72:1077)
