Table A1 also highlights specific rearrangements and mutations linked to SEs in different cancers; for instance, gene fusions like BCR-ABL1 and PML-RARA are often seen in chronic myeloid leukaemia (CML) and acute promyelocytic leukaemia (APL), respectively. The gene discussed is BCR; the disease is chronic myelogenous leukemia, BCR-ABL1 positive.
