The RUNX1 locus, which encodes a transcription factor that is essential for normal hematopoiesis, is a frequent location of chromosomal rearrangements in human hematological malignancies. We report the case of a 78-year-old man with acute myeloid leukemia (AML), M1 subtype (French-American-British classification), with a t(11;21)(p14;q22). Fluorescence in situ hybridization showed a split signal for RUNX1, which indicated that RUNX1 was involved in this translocation. Using 3'-rapid amplification of cDNA ends and reverse transcription-polymerase chain reaction analyses, we found that RUNX1 was fused to C11orf41 on 11p14 and detected two in-frame C11orf41-RUNX1 fusion transcripts. One was a fusion between exon 5 of RUNX1 and exon 13 of C11orf41, and the other was between exon 6 of RUNX1 and exon 13 of C11orf41. This suggested that the RUNX1 breakpoint was in intron 6 and had generated alternative fusion splice variants. A reciprocal C11orf41-RUNX1 fusion was not detected. Thus, we identified C11orf41 as a novel fusion partner of RUNX1 in AML.
