RUNX1 and acute myeloid leukemia: Differences in mutation distribution across WHO17 diagnosis (Supplementary Table S2) were only significant for BCOR/BCORL1, mostly present in AML-RUNX1m (p < 0.001), probably due to their high rate of co-occurrence with RUNX1 mutations, and for STAG2, enriched in AML-MRC (p = 0.03).
