BCR‐ABL rearrangement and Variant’Philadelphia chromosome in de novo acute myelogenous leukaemia FAB subtype M1

Abstract: We report a case of de novo acute myelogenous leukaemia FAB subtype M1 that presents a cytogenetic complex translocation between chromosomes 7, 9 and 22, producing a 'variant' Philadelphia chromosome. Molecular analysis revealed a BCR-ABL rearrangement involving exons b3 and a2 (b3a2). Haematological parameters and genetic analysis again raise the problem of the true nature of this disease, which is briefly discussed.

“…A presença do cromossomo Ph1 em pacientes com LMA é fenômeno raro, sendo descrita em apenas 2% dos casos 5 . Em geral, estão associados aos subtipos FAB M1 e M2 6,7 . Na LMA, podem ocorrer dois tipos de rearranjo bcr-abl: o primeiro com envolvimento da região M-BCR e idêntico ao encontrado na LMC, podendo ser do tipo b3-a2 ou b2-a2 (com ou sem o exon b3), ambos levando à expressão da proteína p210, com intensa atividade tirosina quinase; o segundo envolvendo o primeiro intron do gene BCR ou região m-BCR, com expressão da p190 5 …”
