Such reported cases with the e13a3 transcript showed the Ph chromosome on karyotype analysis. This study reported a rare Ph chromosomepositive CML case with new complex chromosomal aberrations and an e13a3 BCR-ABL transcript that has yet to be established. A four-chromosome translocation involving chromosomal regions 12p11.2, 19q13.3, 9q34.1 and 22q11.2, besides a trisomy 8 and a derivative chromosome 12, were identified using high resolution multicolor banding. Reverse transcription polymerase chain reaction products showed the presence of BCR-ABL fusion transcript e13a3, and this signifies the major BCR breakpoint. The significance of the observed rearrangements and their possible role in the progression of CML was investigated.
