Our results suggest that the CALM-AF10 fusion gene is a constant feature and is involved in the pathogenesis of haematological malignancies with t(10;11)(p13-14;q14-21), showing various and often multilineage phenotypes.     ///    Consistent detection of CALM-AF10 chimaeric transcripts in haematological malignancies with t(10;11)(p13;q14) and identification of novel transcripts..     ///    The CALM-AF10 fusion transcript was detected in all samples.     ///    In RT-PCR analysis there were six isoforms of the CALM-AF10 fusion transcripts and five of AF10-CALM fusion transcripts.     ///    "however, the AF10-CALM fusion was not detected in two patient samples and one cell line.
