Fluorescent in situ hybridization (FISH) analysis is the standard methods for screening ABL1 fusions, which is recurrently translocated in pediatric acute lymphoblastic leukemia (ALL), and potentially targetable by kinase inhibitors. Here we demonstrated a case of B-cell precursor ALL with NUP214-ABL1 fusion, which break-apart FISH assay for ABL1 failed to detect. The cryptic fusion was generated by small duplication from ABL1 to NUP214, which was detected by copy number analysis using genomic microarray and confirmed by PCR. In the context of precision medicine, we should establish how to screen targetable abnormalities for minimizing risk of false-negative.
