NR5A1 expression was not significantly different between KMT2A-r and KMT2A-wt infant ALL patient samples (Supplementary Figure 5A) nor between KMT2A-r and KMT2A-wt leukemia cell lines (Supplementary Figure 5B), and the sensitivity of leukemia cell lines to SID7969543 did not correlate with expression levels of NR5A1 (Supplementary Figure 5C). Here, NR5A1 is linked to acute lymphoblastic leukemia.
