Given the frequency of t(1;19) without the E2A-PBX1 fusion in hematological malignancies, we suggest that MEF2D / DAZAP1 rearrangements might be involved in the pathogenesis of those diseases..     ///    "In addition, exogenous expression of MEF2D-DAZAP1 and DAZAP1-MEF2D promoted the growth of HeLa cells. "    ///    "MEF2D-DAZAP1 and DAZAP1-MEF2D proteins were both located in the nucleus, and MEF2D-DAZAP1 was able to form dimers with MEF2D and HDAC4. "    ///    "Both chimeric transcripts, MEF2D-DAZAP1 and DAZAP1-MEF2D, whose sequences indicated in-frame fusions between MEF2D and DAZAP1, were expressed in TS-2 cells and in bone-marrow cells of the patient from whom the TS-2 was established.
