The term monoclonal B-cell lymphocytosis (MBL) is used to characterize individuals with a circulating population of clonal B-cells and no other features of a lymphoproliferative disorder. Although several recent studies have examined the molecular basis of this condition, the subgroup of MBL lacking CD5 expression has been largely overlooked. In this study, we sequenced a t(2;7) in a patient with persistent but non-progressing CD5(-) MBL. This revealed a breakpoint at 2p11.2 localized to the recombination signal sequence (RSS) of the immunoglobulin ? (IGK) variable gene IGKV3-15, and a breakpoint at 7q21.2 located 520 base pairs (bp) upstream of the transcription start site of cyclin-dependent kinase 6 (CDK6 ). The 7q breakpoint showed perfect sequence homology to the immunoglobulin RSS heptamer, and was located within 3 bp of a t(2;7) junction previously characterized in splenic marginal zone lymphoma (SMZL). These findings highlight a genetic link between CD5(-) MBL and SMZL, and implicate the dysregulation of CDK6 in the emergence of this preclinical disorder.
