CDK5RAP2 and Chronic Eosinophilic Leukemia, Not Otherwise Specified: Here, we determined that a 17-bp homologous sequence in Marinobacter sp. Hb8, Rhodococcus fascians D188, Rhodococcus sp. PBTS2, Micrococcus luteus strain trpE16 and M. luteus NCTC 2665 integrates into the genome of a chronic eosinophilic leukemia patient as part of the linker for the novel CDK5RAP2-PDGFRα fusion gene.
