Concurrence of e1a2 and e19a2 BCR-ABL1 Fusion Transcripts in a Typical Case of Chronic Myeloid Leukemia
Dear Editor, There are three types of BCR-ABL1 fusion transcripts that differ on the basis of the breakpoint in the BCR gene [1]. The major type, encoding p210, has two isoforms, b2a2 (e13a2) and b3a2 (e14a2), and is associated with more than 95% of Ph-positive CML cases. The minor type, encoding p1...

Summary: | Dear Editor, There are three types of BCR-ABL1 fusion transcripts that differ on the basis of the breakpoint in the BCR gene [1]. The major type, encoding p210, has two isoforms, b2a2 (e13a2) and b3a2 (e14a2), and is associated with more than 95% of Ph-positive CML cases. The minor type, encoding p190, is e1a2. The micro type, encoding p230, is e19a2. This micro type is rare, and has been associated with a variety of hematologic malignancies including neutrophilic CML (CML-N), all phases of classical CML, essential thrombocythemia (ET), and acute myeloid or lymphoblastic leukemia [2, 3]. Here, we describe the first case of chronic phase CML concurrently expressing e1a2 and e19a2 BCR-ABL1. KCI Citation Count: 1 |
