While GPR56 displayed an elevated expression as calculated by mean fluorescence intensity (MFI) values in CD34‐positive AML specimens (P < 0.001, see Supporting information, Figure S3A), CLL‐1 expression was higher in CD34‐negative AMLs (P < 0.0001, Supporting Information, Figure S3B). This evidence concerns the gene CLEC12A and acute myeloid leukemia.
