We applied Toblerone to the IKZF1 gene from RNA-seq data from a cohort of 99 B-ALL patients (Figure 2), which included annotations for validated IKZF1 deletion status from microarray and RQ-PCR, as well as other clinical data including fusion status and karyotyping result (Brownet al. 2020). The gene discussed is IKZF1; the disease is precursor B-cell acute lymphoblastic leukemia.
