Velusamy et al. have identified a reciprocal chimeric fusion between the transcripts of yippee-like 5 (YPEL5) and the phosphatase PPP1CB in 97 of 103 (95%) chronic lymphocytic leukaemia (CLL) samples. No evidence was found for a genomic fusion between these loci, indicating a role for RNA-splicing events in forming the chimaeras. YPEL5–PPP1CB produced a PPP1CB protein with reduced activity, and PPP1CB silencing in a CLL cell line increased proliferation and colony formation. The chimaera was not seen in normal cells or in other cancers, so it may have a specific role in CLL pathogenesis.
