Heat map of the derived gene-expression signature associated with the CBFB-MYH11 fusion type (non–type A vs type A with wild-type KIT) in patients with de novo AML and inv(16)/t(16;16). Rows represent gene names and columns represent patients. Genes are ordered by hierarchical cluster analysis. Expression values of the genes are represented by color, with dark blue indicating higher expression and light blue indicating lower expression.
