Identification of a potential role for POU2AF1 and BTG4 in the deletion of 11q23 in chronic lymphocytic leukemia.

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.[1]
