DNMT3A and acute myeloid leukemia: Since T cell clone 1.5.F1DNMT3A showed reactivity against K562 transduced with mutated DNMT3A and the relevant HLA-DQ restriction allele, we tested reactivity of the clone against HLA-DQB1*06:02 or -DQB1*06:03 positive patient-derived AML samples with DNMT3A-R882H.
