Other prognostic indicators such as mutations or abnormal expression of specific genes such as MLL, CEBPA, FLT3, NPM1, DNMT3A, TET2, ASLX1, IDH1, IDH2, WT1, MN1, BAALC, and ERG have been recently described and are particularly useful in assigning risk to patients with diploid AML (intermediate risk cytogenetics group). The gene discussed is FLT3; the disease is acute myeloid leukemia.
