 The BCR-ABL1 fusion gene results from a reciprocal translocation rearrangement, t(9;22)(q34;q11.2), and is a hallmark of chronic myeloid leukemia (CML).     ///    A unique BCR-ABL1 transcript with the insertion of intronic sequence from BCR and ABL1 genes in a patient with Philadelphia-positive chronic myeloid leukemia: a case study..     ///    "This atypical BCR-ABL1 transcript was detected along with a classic e13a2 transcript, using reverse transcription polymerase chain reaction (RT-PCR). "    ///    "To our knowledge, this is the first report of BCR-ABL1 transcript with breakpoint occurring within both BCR and ABL1 introns and fusion of intronic sequences from both BCR and ABL1 genes..
