Within the ‘B-other, with fusion' group, ten cases harboured in-frame fusions previously described in BCP ALL: EP300-ZNF384 (n=3), PAX5-FOXP1 (n=2), P2RY8-CRLF2 (n=2, one of these cases also harboured PAX5-FOXP1), PAX5-DACH1 (n=1), PAX5-ETV6 (n=1), TCF3-HLF (n=1) and TCF3-ZNF384 (n=1). This evidence concerns the gene ZNF384 and acute lymphoblastic leukemia.
