We detected an ALK rearrangement using fluorescence in situ hybridization, identified the ALK fusion partner by using RNA transcriptome sequencing, and demonstrated the RANBP2-ALK fusion transcript by reverse transcriptase--PCR and Sanger sequencing.     ///    "Our results, together with a literature review, suggest the RANBP2-ALK fusion combined with monosomy 7 may be related to a unique clonal hematologic disorder of childhood and adolescence, characterized by myelomonocytic leukemia and a poor prognosis..
