BCR-ABL gene rearrangement assay methodMethods for assaying biological samples for bcr-abl translocation rearrangements and reporting the results of such assays which are useful in the diagnosis of CML and/or ALL are provided.Richard W. Tseng
Fig. 7: Cell-of-transformation model for BCR-ABL1 lymphoblastic leukemia subtypes. The disease originates from the rearrangement of BCR-ABL1 in a multipotent stem cell (HSC or MPP), which is the cell-of-origin. BCR-ABL1 increases cell proliferation and impairs DNA damage response. It then...
The Philadelphia chromosome (Ph+) reflects a balanced reciprocal translocation between the long arms of chromosomes 9 and 22 [t(9;22)(q34;q11.2] involving the BCRand ABL genes. At present, detection of BCR/ABL gene rearrangements is mandatory in precurso

The BCR/ABL gene rearrangement is cytogenetically visualized in most chronic myeloid leukemia (CML) cases. About 5–10 % of CML patients lack its cytogenetic evidence, however, shows BCR/ABL fusion by molecular methods. We describe two CML patients with Philadelphia (Ph) negative (−ve) ...
CMML is characterized by monocytosis and dysplasia. Blasts have to be less than 20%; otherwise, this would beacute leukemia. Also, the Philadelphia chromosome is absent. A test forBCR–ABLgene rearrangementis negative. ▪ Atypical CML is characterized byleukocytosisresembling CML. However, dysplas...

BCR-ABL p210伴CBFβ-MYH11融合基因双表达的CML-BC病例罕见,发病机制及预后尚未明确,相应的诊疗仍需要更多的临床病例进行继续探索。临床上收治进展期CML有条件时推荐进行融合基因筛查。 摘要 临床资料 四、治疗 讨论 参考文献 参考文献 [1] Naiyer N , Zaslav AL , Ahmed T ,et al. A rare case of B-ly...
The term “bcr/abl translocation” or “t(9; 22)” as used herein is an aberrant gene rearrangement between the abl protooncogene on chromosome 9 and the breakpoint cluster region (bcr) on chromosome 22. The breakpoint is constant at the abl locus occurring 5′ to exon 2 in an approxim...
The primers and probes set forth above have been designed to be able to amplify and detect all three translocations of the bcr-abl gene, namely; e1a1, ba2a2 and b3a2, without interfering with each other and providing highly reproducible results. It is to be understood that one of ordinar...
