Abstract

We identified a novel familial case of clear‐cell renal cancer and a t(3;6)(q12;q15). Subsequent cytogenetic and molecular analyses showed the presence of several abnormalities within tumour samples obtained from different patients. Loss of the der(3) chromosome was noted in some, but not all, of the samples. A concomitant VHL gene mutation was found in one of the samples. In addition, cytogenetic and molecular evidence for heterogeneity was obtained through analysis of several biopsy samples from one of the tumours. Based on these results and those reported in the literature, we conclude that loss of der(3) and subsequent VHL gene mutation may represent critical steps in the development of renal cell cancers in persons carrying the chromosome 3 translocation. Moreover, preliminary data suggest that other (epi)genetic changes may be related to tumour initiation. © 2001 Wiley‐Liss, Inc.
