We generated single cell gene expression data from 39,375 pediatric bone marrow mononuclear cells (BMMCs) from eight cALL patients of common subtypes (4 ETV6-RUNX1, 2 High Hyper Diploid and 2 T-ALL) having >50% blasts and 3 healthy donors (Tables 1 and 2). This evidence concerns the gene ETV6 and acute lymphoblastic leukemia.
