Abstract
Zinc-finger protein 384 (ZNF384) gene fusions with EP300 have recently been described as a recurrent fusion in B-cell acute lymphoblastic leukemia (B-ALL) with a good response to conventional chemotherapy, suggesting a favorable prognosis. Herein, we report on a female patient aged 12 years with uninformative conventional chromosome and B-ALL panel fluorescence in situ hybridization studies with chromosomal microarray showing multiple copy number gains, including relative gains in the ZNF384 (12p13.31) and EP300 (22q13.2) gene regions, suggesting a cryptic EP300/ZNF384 fusion. Ultimately, a next-generation sequencing assay, mate pair sequencing, was utilized to confirm EP300/ZNF384 fusion in this B-ALL clone, which may confer a favorable overall prognosis and potential targeted therapy.
