PG - 951-954 AB - Chronic myeloid leukemia (CML) is a pluripotent hematopoietic stem cell disorder almost always characterized by the presence of the Philadelphia chromosome (Ph), usually due to t(9;22)(q34;q11). The presence of Ph results in the formation of the BCR/ABL fusion gene, which is a constitutively activated tyrosine kinase. Approximately 1% of CML patients appear to have a Ph-negative karyotype but carry a cryptic BCR/ABL fusion that can be located by fluorescence in situ hybridization (FISH) at chromosome 22q11, 9q34 or a third chromosome. This study investigated a rare Ph-negative CML case with insertion of the 3' ABL region into the long arm of derivative chromosome 1 but lacking the 5' BCR region on der(22).
