The BCR-ABL fusion gene can be seen in CML patients, it is also found in other types of leukemia patients, such as acute myeloid leukemia (AML) patients (Bucur et al., 2013), B-cell acute lymphoblastic leukemia (B-ALL) patients (Zhou et al., 2018), and mixed phenotype acute leukemia (MPAL) patients (Alexander et al., 2018). Here, BCR is linked to acute lymphoblastic leukemia.
