Clinical Significance. BCR-ABL1 Gene Rearrangement, Quantitative, PCR - The Philadelphia Chromosome (Ph) is a translocation between chromosome 9 and 22 t (9; 22) (q34; Q11) that is found in more than 90-95% of chronic myeloid leukemia (CML), and in 20-25% of adult and 2-10% of childhood acute lymphoblastic leukemia (ALL).

Other less frequent transcript subtypes, such as e1a2, e2a2, e6a2, e19a2, e1a3, e13a3 and e14a3, have been sporadically reported.1 Different subtypes of BCR-ABL1 Schematic representation of the ABL1 and BCR genes and the BCR-ABL1 kinase. (A) BCR contains 23 exons. Exons 1′ and 2′ of BCR are alternative exons within the first intron. The 3 main breakpoint cluster regions (m-bcr, M-bcr, and μ-bcr) in BCR are presented.ABL1 contains 2 alternative first exons (1b and 1a). The dashed arrows represent the breakpoints within ABL1. The BCR/ABL gene fusion is the genetic signature of the hematologic malignancy chronic myeloid leukemia (CML). It is also present in a smaller subset of predominantly adult onset B cell-acute lymphoblastic leukemia (B-ALL), where it confers a poor prognosis when treated with … Genes BCR and ABL1 BCR-ABL1 Fusion is present in 0.21% of AACR GENIE cases, with chronic myeloid leukemia, breast invasive ductal carcinoma, unknown, B-cell lymphoblastic leukemia/lymphoma, and acute myeloid leukemia having the greatest prevalence [ 4 ].

The BCR gene product has serine/threonine kinase activity and is a GTPase-activating protein for p21rac.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. 2020-09-20 NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine. The BCR gene is located on chromosome 22q11.2, the site of the translocation breakpoint in CML (Prakash and Yunis, 1984).Croce et al. (1987) demonstrated that there are in fact 4 BCR genes, all located in the 22q11.2 band. By studying mouse-human hybrid cells with breakpoints at various sites in that region, they concluded that the order of loci is centromere--BCR2, BCR4, IGL--BCR1--BCR3--SIS.

The ABL1 gene fusion occurred at the N-terminus end of the BCR gene results in oncogenic activity. Apart from the ABL1 gene, the BCR gene is also involved in the fusion with some other genes such as MLLT4, PXN, CD117, FES, Grb2, GRB10, HCK, XPB and SOS1. The ABL1 gene on chromosome 9 is placed in juxtaposition to a downstream part of BCR gene on chromosome 22, resulting in a chimeric oncoprotein with a constitutively tyrosine kinase activity 3, 4. Patients with gene rearrangement had a greater frequency of CD66c, CD13 and CD33 positivity compared with BCR/ABL1-negative cases.

BCR-ABL1 refers to a gene sequence found in an abnormal chromosome 22 of some people with certain forms of leukemia. Unlike most cancers, the cause of chronic myelogenous leukemia (CML) and some other leukemias can be traced to a single, specific genetic abnormality in one chromosome.

The BCR-ABL hybrid gene, the main product of the t(9;22)(q34;q11) translocation, is found in the leukaemic clone of at least 95% of CML patients. The fusion protein encoded by BCR-ABL varies in size, depending on the breakpoint in the BCR gene. The ABL1 gene provides instructions for making a protein involved in many processes in cells throughout the body. The ABL1 protein functions as a kinase, which is an enzyme that changes the activity of other proteins by adding a cluster of oxygen and phosphorus atoms (a phosphate group) at specific positions.
