Abstract

Cytogenetic analysis of predisposition syndromes has played a critical role in the elucidation of the genetics of Wilms' tumor (WT). Therefore, we became interested in a patient who presented with a WT and a nephrogenic rest in the contralateral kidney (suggestive of a predisposition) and a de novo t(1;7)(q42;p15) constitutional translocation as the only visible cytogenetic abnormality. He also had bilateral radial aplasia and other skeletal abnormalities, but there was no manifestation of any syndrome previously associated with WT. In the tumor, the translocation was retained, and the other 7p region was lost by the formation of an isochromosome i(7q). Here, we report the localization of the chromosome 7 breakpoint within a yeast artificial chromosome (YAC) contig by using fluorescence in situ hybridization (FISH), localizing the breakpoint between markers sWSS355 and sWSS1449. A number of YACs span the breakpoint and, thus, contain the region that is disrupted by the translocation. This may represent the site of a novel tumor suppressor gene that is involved in WT and also in normal renal development. (C) 1996 Wiley-Liss, Inc.
