Mutational profile of BCL11B-a AL. Oncoprint heat map showing all sequence variants detected in BCL11B-a AL cases. In addition to somatic mutations (dark green), variants in which the somatic or germline origin could not be definitively assessed (light green) are indicated. Additional gene alterations are represented by different colors. Mutational analysis was not performed in cases 15 and 19 because of lack of material. cnLOH, copy neutral loss of heterozygosity.
