PG - 1248-51 AB - We developed dual-color split fluorescence in situ hybridization (FISH) assays to detect AF10 and/or CALM rearrangements. Among nine cases of acute leukemia with translocation breakpoints at 10p13 and 11q14-21, a CALM/AF10 rearrangement was found in seven and was confirmed by reverse transcriptase polymerase chain reaction (RT-PCR) in all. In 2/7 cases, FISH detected CALM/AF10 in extramedullary leukemic infiltrations in the mediastinum and breast. As expected, FISH was less sensitive than RT-PCR for disease monitoring of CALM-AF10 positive cases. This new FISH assay reliably discriminates between MLL/AF10 and CALM/AF10 genomic rearrangements, identifies variant and complex CALM/AF10 translocations and detects the CALM/AF10 rearrangement in extramedullary leukemic infiltrations.
