Consequently, we neither identified a fusion transcript by transcriptome sequencing nor a MYB/MNX1 fusion protein by Western blot, but we observed instead high expression of MNX1 at both the transcript and the protein level (Supplementary Fig. 1) with 191.7 transcripts per kilo base million (TPM) in GDM-1 as compared to <3 TPM in 41 unpublished AML cases without MNX1-associated rearrangements. The gene discussed is MYB; the disease is acute myeloid leukemia.
