ABSTRACT
Deletions of 11q in chronic lymphocytic leukemia (CLL) are usually associated with progressive disease and poor prognosis. A novel translocation within the previously identified 11q minimal region has been defined in a patient with CLL. The breakpoint is between genes POU2AF1 and BTG4. POU2AF1 is a B-cell-specific transcriptional coactivator, and BTG4 is a member of the BTG family of negative regulators of the cell cycle, making both of them good candidate genes for the pathogenesis of 11q- CLL. POU2AF1 was observed to be differentially expressed in the cells of patients with CLL compared to its expression in normal B cells in the absence of mutations. This may reflect ongoing stimulation and active accessory signaling in CLL cells. BTG4 could contribute to CLL pathogenesis following inactivation by haploinsufficiency.
