Novel and established EWSR1 gene fusions and associations identified by next-generation sequencing and fluorescence in-situ hybridization

EWSR1 is a ‘promiscuous’ gene that can fuse with many different partner genes in phenotypically identical tumors or partner with the same genes in morphologically and behaviorally different neoplasms. Our study set out to examine the EWSR1 fusions identified at our institution over a 3-year period, using various methods, their association with specific entities and possible detection of novel partners and associations. Sixty-three consecutive...
