Similar to CD34, low expression of HLA-DR was detected on t(15;17) AML (Supplementary Figures 5, 3B–D) and MLL AML blasts (Figures 4B,D), with increased expression on t(8;21) AML (Supplementary Figures 5, 2C) and inv(16) AML blasts (Supplementary Figures 5, 4B). The gene discussed is KMT2A; the disease is acute myeloid leukemia.
