Chronic myeloid leukaemia (CML) is a pluripotent haematopoietic stem cell disorder defined by expression of the BCR/ABL1 fusion gene, a constitutively activated tyrosine kinase, harbored by the Philadelphia chromosome (Ph), which is a result of a t(9;22)(q34;q11) or a related variant translocation [1]. Here, ABL1 is linked to chronic myelogenous leukemia, BCR-ABL1 positive.
