In addition, we provided preliminary data of MLLre leukemia using RNA-seq data of the THP1 cell line with KMT2A-MLLT3 (MLL-AF9) fusion (Guarnerio et al., 2016) and unpublished data of two specimens of infant ALL with KMT2A-MLLT1 (MLL-ENL) fusions (Supplementary Table 3). This evidence concerns the gene MLLT1 and leukemia.
