PG - 36-9 LID - 10.1016/j.cancergencyto.2009.02.012 [doi] AB - We report a rare cryptic ins(12;9)(p13;q34q34), a chromosomal abnormality involving the ABL1 (9q34) and the ETV6 (alias TEL; 12p13) genes, detectable only by fluorescence in situ hybridization (FISH), in a patient with Philadelphia-negative chronic myeloid leukemia (CML). Using reverse 4',6-diamidino-2-phenylindole banding on metaphase cells, FISH analysis with BCR/ABL dual-fusion and ETV6 break-apart probes showed that a third ABL signal was inserted into 12p, splitting the ETV6 signal into two adjacent signals. CML patients with an ABL1/ETV6 fusion historically have demonstrated a variable and sometimes transient response to treatment with imatinib mesylate, which was also the case in the present patient.
