Abstract

Chromosome translocations found in neoplasms often result in the creation of hybrid genes encoding chimeric proteins. Desmoplastic small round cell tumor (DSRCT) is a recently described aggressive malignancy associated with a unique chromosomal translocation t(11;22)(p13; q12). This translocation has recently been characterized, revealing the rearrangement and fusion of the WT1 gene on chromosome 11 to the EWS gene on chromosome 22. Fusion of these two genes results in the production of a putative oncogenic protein composed of the zinc finger DNA-binding domains of WT1 linked to the potential transcriptional regulatory domains of EWS. The typical chimeric transcript consists of the first 7 exons of EWS and the last 3 exons of WT1. We report here the first case of DSRCT with a variant EWS-WT1 chimeric product that includes 9 exons of EWS and 3 exons of WT1.
