IKZF1 and acute myeloid leukemia: We also provided a comparison of IKZF1‐positive gene expression profile with other non‐IKZF1 AML using the same 1267 genes expression, and further demonstrated that IKZF1 N159S may define a separate molecular subtype with unique GEP in all our AML cases, even within the subcluster of myelodysplasia‐related/‐like AML (Figure S3A).
