CD40LG and B-cell chronic lymphocytic leukemia: Küppers et al. reported 2 adults and 2 pediatric CLL cases with t(2;14) (p13;q32.3); all of these patients had unmutated IGHV genes; interestingly one patient was diagnosed with CLL clinically, but the lymph node biopsy was consistent with lymphoplasmacytic lymphoma/immunocytoma expressing monoclonal IgM.
