Unfortunately insufficient material was available to perform specific FISH to further demonstrate the presence of the BCL11A-IGH translocation, but analysis of the oncogenes present in chromosome 2p16 renders BCL11A as the only potential candidate with demonstrated oncogenic capacity in CLL/SLL [13]. IGHV gene mutation analysis was reported as unmutated. Here, BCL11A is linked to B-cell chronic lymphocytic leukemia.
