Except for TP53-mutated AMLs, leukemic blasts demonstrated a tendency for a higher CD9 GMFI as compared to normal myeloid blasts with APL, AML with CBFB::MYH11, and AML with KMT2Ar expressing the highest levels (Figure 4, Figures S2 and S3). The gene discussed is CBFB; the disease is acute myeloid leukemia.
