PG - 74-7 AB - We performed chromosome analysis on the bone marrow of a patient with BCR/ABL negative chronic myelogenous leukemia (CML). By interphase fluorescence in situ hybridization (FISH), an extra ABL signal was present in interphase nuclei and appeared to be located at 17p in the metaphase cells. Chromosome analysis showed a subtle abnormality at 17p13 and 12p13 but no visible rearrangement at 9q34 (ABL). Additional FISH experiments disclosed a rearrangement between the short arms of chromosomes 12 and 17 at approximately bands 12p13 and 17p13, respectively. In addition, subtelomeric FISH analysis confirmed the presence of terminal 12p at 17p13 and showed terminal 9q34 to be intact on each chromosome 9. Taken together, these results indicated a rearrangement involving chromosomes 9, 12, and 17 that suggested the possibility of juxtaposition of part of the ETV6 (also known as TEL) locus (12p13) with a portion of ABL (9q34) together at 17p13. The ETV6/ABL fusion was confirmed by RT-PCR, which showed that the first 5 exons of ETV6 were fused in frame with ABL at exon 2. Wild-type ETV6 and ABL were also expressed, in accordance with the FISH results that showed no loss of the second ETV6 or ABL allele.
