 We report a case of acute myeloid leukemia (AML) with two unrelated clones, one of which was t(11;17)(q23;q25) carrying MLL-SEPT9 fusion transcripts.     ///    Emergence of two unrelated clones in acute myeloid leukemia with MLL-SEPT9 fusion transcript..     ///    Reverse transcriptase-polymerase chain reaction and sequencing analyses demonstrated MLL-SEPT9 fusion transcripts with the breakpoint of MLL exon 8/SEPT9 exon 2 and MLL exon 9/SEPT9 exon 2.
