Chronic Myeloid Leukemia (CML) is a clonal hematopoietic disorder generated by a t(9;22)(q34;q11) translocation resulting in a BCR/ABL oncogene[1], [2] that encodes for a tyrosine kinase BCR/ABL-p210 oncoprotein[3]. This evidence concerns the gene ABL1 and chronic myelogenous leukemia, BCR-ABL1 positive.
