Wilms' tumor has served as a model of multiple genetic alterations in
childhood cancer. This review summarizes work in our laboratory identi
fying several of these alterations. These include the localization to
11p15 of an embryonal tumor suppressor gene and at least one gene for
Beckwith-Wiedemann syndrome, which predisposes to Wilms' tumor; as wel
l as a novel mutational mechanism in man, loss of imprinting. (C) 1996
