- In recent years, a subgroup of B‐cell precursor acute lymphoblastic leukemia (BCP ALL) without an established abnormality (“B‐other”) has been shown to be characterized by rearrangements of ABL1 , ABL2 , CSF1R , or PDGFRB (a.k.a. ABL‐class genes). Using FISH with probes for these genes, we screened 55 pediatric and 50 adult B‐other cases. Three (6%) of the adult but none of the childhood B‐other cases were positive for ABL‐class aberrations. RT‐PCR and sequencing confirmed a rare SFPQ‐ABL1 fusion in one adult B‐other case with t(1;9)(p34;q34). Only six SFPQ ‐ABL1 ‐positive BCP ALLs have been reported, present case included. A review of these shows that all harbored fusions between exon 9 of SFPQ and exon 4 of ABL1 , that the fusion is typically found in adolescents/younger adults without hyperleukocytosis, and that IKZF1 deletions are recurrent. The few patients not treated with tyrosine kinase inhibitors (TKIs) and/or allogeneic stem cell transplantation relapsed, strengthening the notion that TKI should be added to the therapy of SFPQ ‐ABL1 ‐positive BCP ALL.
