Using deFuse, we searched for the TMPRSS2-ERG fusion in the NCI-H660 prostate cell line dataset, the three fusions previously identified in the CML dataset (SRA accession: SRR018269) and the 11 fusions in melanoma libraries identified by Berger et al. [16]. This evidence concerns the gene TMPRSS2 and chronic myelogenous leukemia, BCR-ABL1 positive.
