In a total of 2,293 cases across five cohorts [three qRT-PCR cohorts and public RNA-seq data from TCGA-LAML (1) and BEAT-AML (35)], we estimated the frequency of MNX1-expressing samples to be 1.4% of all AML cases (Supplementary Table S13). The gene discussed is MNX1; the disease is acute myeloid leukemia.
