However, the incidence of NPM1-A(+) was clearly lower in AML with recurrent genetic abnormalities, at 1/11 (9.1%), compared to AML with myelodysplasia-related changes (AML-MRC) at 4/11 (36.4%), therapy-related myeloid neoplasms at 3/15 (20.0%), and AML not otherwise specified (NOS) at 15/65 (27.7%). Here, NPM1 is linked to myeloid neoplasm.
