Associations include:

  • Beckwith Wiedemann syndrome
  • Bloom syndrome
  • Sotos syndrome
  • von Hippel-Lindau syndrome
  • retinoblastoma

A genetic predisposition to Wilms' tumour is found in overlapping syndromes:

  • a germline mutation is thought to be the cause of about 10%-15% of Wilms tumor.
    • WT1 germline mutations give rise to WAGR syndrome, Denys-Drash syndrome, Frasier syndrome, and isolated Wilms tumor (i.e., Wilms tumor with no evidence of an underlying syndrome).
      • WAGR syndrome - Wilms tumour-aniridia-genital anomalies-retardation

Notes (2):

  • models of Wilms tumor development propose that a genetic mutation predisposes to nephrogenic rests (benign foci of embryonal kidney cells that persist abnormally into postnatal life)
    • nephrogenic rests are characterized as intralobar or perilobar
      • in general, intralobar rests (usually single lesions within the renal lobe, renal sinus, or calyceal walls)
        • associated with the WAGR (Wilms tumor-aniridia-genital anomalies-retardation) syndrome and Denys-Drash syndrome (DDS)
      • in general, perilobar rests (usually multiple lesions in the periphery of the renal lobe)
        • associated with Beckwith-Wiedemann syndrome (BWS) and hemi-hyperplasia
    • however, the association between type of nephrogenic rest and predisposition syndrome is not absolute
