Finally, we applied Slinker to three childhood B-Cell Acute Lymphoblastic Leukemia samples obtained from the Royal Children’s Hospital (RCH), that harboured various IKZF1 deletions; these were validated in DNA using a multiplex-ligation-dependent probe amplification (MLPA) assay (Table 1).Figure 6A depicts an exon 4-7 deletion within one such case compared to two other leukemia samples in the RCH cohort. Here, IKZF1 is linked to acute lymphoblastic leukemia.
