TRIP11 and myeloid neoplasm: Translocation of 5q31-33, PDGFRB occur rarely in therapy-related myeloid neoplasm and there has been two identified PDGFRB partner genes located at 14q32, TRIP11 and KIAA1509.<h4>Results</h4>The TRIP11-PDGFRB fusion was identified in a patient with therapy-related myeloid neoplasm with t(5;14)(q33;q32) after treatment of APL using conventional cytogenetics, fluorescence in situ hybridization (FISH) and molecular methods.
