The AML panel in the cytogenetics FISH study was negative for RUNX1T1/RUNX1 (ETO/AML1), KMT2A (MLL), PML/RARA, CBFB rearrangement, negative for monosomy 5, and deletion of CSF1R/RPS14 on the long arm of chromosome 5 at q33, negative for monosomy 7, and deletion of MDFIC on the long arm of chromosome 7 at q31. Here, RUNX1T1 is linked to acute myeloid leukemia.
