Due to the lack of detailed mutation information from pediatric AML samples, we could only check the mutation status available on five genes with high clinical relevance (FLT3, NPM1, KIT, CEBPA, and WT1) and on three oncogenic gene fusions (RUNX1-RUNX1T1, CBFB-MYH11, and PML-RARA). The gene discussed is RUNX1T1; the disease is acute myeloid leukemia.
