Vegliante et al. (2011) demonstrated the increased expression of SOX11 mRNA in ETV6-RUNX1 (E/R) and TCF3-rearranged B-cell precursor acute lymphoblastic leukemia (BCP-ALL)30, whereas Nordlund et al. (2012) and Busche et al. (2013) observed the prominent expression of SOX11 in the E/R subtype of ALL31,32. This evidence concerns the gene TCF3 and precursor B-cell acute lymphoblastic leukemia.
