t(9;22) generates the BCR-ABL fusion gene, the hallmark of chronic myeloid leukemia (CML) but also found in acute lymphoblastic leukemia (ALL). Multiple chimeric transcripts translate to proteins of 190 or 210 kd and, rarely, 230 kd. CML typically carries p210 BCR-ABL while ALL is most often associated with p190. Detection and quantification of these fusion transcripts is useful in clinical management. We have exploited the unique melting profiles of these transcripts to design a new, simple, and cost-effective assay based on monochrome multiplex real-time RT-PCR for identification and quantification of each of these transcripts (b3-a2, b2-a2, and e1-a2) without further manipulation. The sensitivity of this assay was 10−4for e1-a2 and 10−5for b3-a2/b2-a2, which is appropriate for detection of minimal residual disease (MRD). Inter- and intra-assay variation was minimal. We applied this assay to assess the distribution of p190 and p210 in 260 childhood ALL samples from India. BCR-ABL was detected in 19 (7.3%), including one T-ALL. Eight patients (3.1%) demonstrated mBCR-ABL (p190) and 11 (4.2%) had MBCR-ABL (p210). Transcript levels varied markedly (up to 3000-fold) but e1-a2 were generally expressed at higher levels than b3/b2-a2 (P = 0.05). This simple real-time multiplex assay can thus be easily applied to monitor patients with ALL as well as CML.
