Chronic myeloid leukaemia (CML) is a malignant myeloproliferative disorder of primitive pluripotent stem cells arisen from the chromosomal translocation [t(9;22)(q11;q34)], which gives rise to the BCR-ABL1 fusion oncogene [1]. Here, ABL1 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
