A novel variant form of MLL-ELL fusion transcript with t(11;19)(q23;p13.1) in chronic myelomonocytic leukemia transforming to acute myeloid leukemia..     ///    "Thus, a possibility is raised that the unique clinical presentation of the present case with t(11;19)(q23;p13.1) might be related to the variant form of MLL-ELL.. "    ///    "It is deduced that the variant form of MLL-ELL may be defective not only in inhibition of transcription initiation, but also in transcriptional elongation. "    ///    Sequence analysis of reverse-transcriptional polymerase chain reaction product revealed a novel variant form of MLL-ELL transcript in which MLL exon 10 was fused to ELL exon 3.     ///    "MLL has been fused to ELL exon 2 in all the previously reported MLL-ELL transcripts, which have always been associated with AML.
