FUT4 and chronic myelogenous leukemia, BCR-ABL1 positive: To address this key point, and in the absence of publicly available RNA‐seq data for CML cells, we used RNA‐seq data from PB‐CD34+ cells to determine a list of candidate genes the expression of which could be repressed by aberrant DNA methylation in CP‐CML CD34+CD15− cells (i.e., genes that are expressed in PB‐CD34+ cells (rpkm > 1) and the promoter of which is a hypermethylated DMR in CML).
