(General Instructions – The focus of these pages is the clinically significant genetic alterations in each disease type. This is based on up-to-date knowledge from multiple resources such as PubMed and the WHO classification books. The CCGA is meant to be a supplemental resource to the WHO classification books; the CCGA captures in a continually updated wiki-stye manner the current genetics/genomics knowledge of each disease, which evolves more rapidly than books can be revised and published. If the same disease is described in multiple WHO classification books, the genetics-related information for that disease will be consolidated into a single main page that has this template (other pages would only contain a link to this main page). Use HUGO-approved gene names and symbols (italicized when appropriate), HGVS-based nomenclature for variants, as well as generic names of drugs and testing platforms or assays if applicable. Please complete tables whenever possible and do not delete them (add N/A if not applicable in the table and delete the examples); to add (or move) a row or column in a table, click nearby within the table and select the > symbol that appears. Please do not delete or alter the section headings. The use of bullet points alongside short blocks of text rather than only large paragraphs is encouraged.

Gene Rearrangements

The t(9:22)(q34.1;q11.2) results in the formation of the Ph chromosome and the chimeric BCR-ABL1 fusion gene. In AML, ~70 - 80% cases with BCR::ABL1 harbor p210 transcripts, and 50-60% cases with additional chromosomal abnormalities[1][2][3][4]. The most common BCR-ABL1 transcripts p190 and p210 have been detected in nearly equal distribution[5]. Since p190 is very rare in CML (p210 transcripts in >99% of cases), the presentation with a p190 transcript is in favor of the diagnosis of AML rather than CML[6].

ABL1 BCR::ABL1 The pathogenic derivative is the der(22) resulting in fusion of 5’ BCR and 3’ABL1. t(9;22)(q34;q11.2) Common ~90-95% (CML)[7]; Rare ~0.5 - 3% (AML)[8]. Diagnosis: BCR-ABL1 positive AML is an emerging entity. The proliferation of BCR-ABL1 positive blasts present a diagnostic dilemma. While it may be difficult, it is essential to distinguish between BCR-ABL1 positive AML and Chronic Myeloid Leukemia in Myeloid Blast Crisis (CML-MBC), in order to choose the most appropriate therapy (e.g., intensive induction chemotherapy versus tyrosine kinase inhibitor (TKI) followed by an early allogeneic stem cell transplant). After the exclusion of acute leukemia of ambiguous lineage (a separate entity according to WHO) by flow cytometry, it is helpful to note any past history of antecedent hematological disease. Compared to CML-MBC, a higher percentage of blasts (median: 47% vs 13%), a lower percentage of basophils (median: 0% vs 2.5%) and absolute basophil count, a lower frequency of splenomegaly (25% vs 65%), lower cellularity, fewer dwarf megakaryocytes, and normal M:E ratio favor the diagnosis of BCR-ABL1 positive AML[2][1]. The detection of p190 transcript and the occurrence of any BCR-ABL1 transcript in less than 100% of metaphases supports the diagnosis of AML rather than CML. Persistent CCyR (Complete Cytogenetic Response) after conventional chemotherapy is unusual for CML-MBC and supports the diagnosis of BCR-ABL1 positive AML[5]. Karyotype analysis that identifies the t(9;22)(q34;q11.2) translocation, either alone or in conjunction with additional chromosomal abnormalities, characterizes BCR-ABL1 positive AML[1][2]. In addition, molecular methods including dual-colour dual-fusion FISH, RT-PCR, qPCR, and RNA or DNA sequencing are used to identify all common breakpoint variants when applicable.


Prognosis: The overall prognosis of BCR-ABL1 positive AML is poor, with a median survival time of <9 months[9][1]. The National Comprehensive Cancer Network (NCCN) Clinical Practice Guidelines in Oncology for AML categorize this entity into the poor-risk group, comparable with complex aberrant karyotype AML[10]. It appears that the prognosis of BCR-ABL1 positive AML depends more on the genetic background (concurrent aberrations) than on BCR-ABL1 itself. Unlike in CML, BCR-ABL1 does not appear to be the key driver in AML though may provide a proliferative advantage to a particular BCR-ABL1 positive subclone.


Therapeutics: There is currently no standardized treatment approach for BCR-ABL1 positive AML. Therapy with TKI alone does not produce sustained responses in BCR-ABL1 positive AML[1]. This may be due to a very rapid clonal evolution, resulting in resistance in a much higher proportion of patients and in a significantly shorter time than in CML[5].Venetoclax and TKI combination regimens have shown good response in some studies[11].

Yes (WHO, NCCN) The t(9;22) is diagnostic of CML in the appropriate morphology and clinical context[12][13]. This fusion is responsive to targeted therapy such as Imatinib (Gleevec)[14].


BCR::ABL1 is generally favorable in CML[15][16].

Three BCR-ABL chimeric proteins result from varying mRNA fusions of the ABL and BCR genes. The most common breakpoint occurs in BCR intron 13 or 14, fusing to ABL1 exon a2 (e13a2, e14a2), yielding a 210 kilodalton protein (p210 BCR-ABL1) found in 95% of CML cases. A rare alternative (<1%) is the e19a2 fusion, producing a 230 kilodalton protein (p230 BCR-ABL1), a marker for neutrophilic-chronic myeloid leukemia. The e1a2 fusion results in the p190 BCR-ABL1 protein, prevalent in B cell ALL, less common in AML, and rare in CML[8].


There is a single case report of a patient achieving molecular remission with dasatinib and chemotherapy[17].


Outcome of patients < 50 years of age with TKI pretreated BCR::ABL1 positive AML receiving allogeneic stem cell transplant is relatively favorable[18].


Survival status postallogeneic transplantation appears similar to intermediate risk AML, with one report demonstrating 3 year overall survival of 73%[19].

Individual Region Genomic Gain/Loss/LOH

AML with BCR-ABL1 carries unique genome imbalances. Nacheva et al., used array comparative genomic hybridization (CGH) to perform a comparative study between several BCR-ABL1 positive entities. BCR-ABL1 positive AML displays characteristic of lymphoid disease (found in BCR-ABL1 positive ALL and CML): deletions of IKZF1 and/or CDKN2A/B genes were recurrent findings in BCR-ABL1 positive AML as well as cryptic deletions within the immunoglobulin IGH and T cell receptor gene (TRG alpha) complexes[20]. Importantly, these aberrations were found to be absent in CML-MBC and hence they are potentially a helpful diagnostic tool for difficult cases.

Most cases will have monosomy 7/Del(7q), trisomy 8 or complex karyotypes in addition to the t(9;22)(q34.1;q11.2)[21].

8 Gain chr8 Unknown D,P No Common recurrent secondary finding for t(8;21)[22][23].

Characteristic Chromosomal or Other Global Mutational Patterns

Additional chromosomal aberrations are infrequently seen in BCR-ABL AML, it has been described together with different class II aberrations such as CBFB-MYH11, RUNX1- RUNX1T1 and PML-RARA[5]. In AML, BCR-ABL1 seems to cooperate with several AML-specific aberrations such as inv(16), t(8;21) and myelodysplasia-related cytogenetic aberrations[5][24]. (For diagnostic purpose, note that inv(16) is not restricted to AML and can also be found in CML-MBC). Additional chromosomal aberrations, such as an additional Ph chromosome, trisomy 19 and isochromosome 17q seen in CML MBP are infrequently seen in AML with BCR::ABL1.

Genes and Main Pathways Involved

The BCR gene product has serine/threonine kinase activity and is a GTPase-activating protein for p21rac[25]. The ABL1 gene is a proto-oncogene that encodes a protein tyrosine kinase involved in a variety of cellular processes, including cell division, adhesion, differentiation, and response to stress. The activity of this protein is negatively regulated by its SH3 domain, whereby deletion of the region encoding this domain results in an oncogene[26]. The t(9,22)(q34;q11) leads to the formation of a Philadelphia chromosome and generates an active chimeric BCR-ABL1 tyrosine kinase. The fusion gene is created by juxtaposing the ABL1 gene on chromosome 9 (region q34) to a part of BCR (breakpoint cluster region) gene on chromosome 22 (region q11). This is a reciprocal translocation, creating an elongated chromosome 9 (der 9), and a truncated chromosome 22 (the Philadelphia chromosome, 22q-), the oncogenic BCR-ABL1 being found on the shorter derivative 22 chromosome[27][28]. This gene encodes for a BCR-ABL1 fusion protein, a tyrosine kinase. Tyrosine kinase activities are typically regulated in an auto-inhibitory manner, but the BCR-ABL1 fusion gene codes for a protein that is continuously activated, causing unregulated cell division. This is a result of the replacement of the myristoylated cap region which causes a conformational change rendering the kinase domain inactive, with a truncated portion of the BCR protein[29]. The enzyme is responsible for the uncontrolled growth of leukemic cells which survive better than normal blood cells. As a result of BCR/ABL1 variable splicing (fusion RNA and hybrid proteins), two transcripts p190 and p210 are found for BCR-ABL1 positive AML.
