As almost all cases with HOXA13-T and NUP98-related fusion events belong to the ETP ALL subtype and were associated with ectopic expression of the HOXA11-A13 genes (Fig. 4a and Supplementary Fig. 4d), we extended our analysis by integrating our in-house data with data published by Liu et al.6 to further characterize the HOXA11-A13+ group. The gene discussed is HOXA13; the disease is acute lymphoblastic leukemia.
