Study Description

A subset of CCND1-negative mantle cell lymphoma MCL (CCND1- MCL) has been recognized, and around half of them harbor CCND2 translocations. To identify other potential mechanisms driving MCL pathogenesis we investigated CCND1− MCL by by whole genome/exome sequencing. We identified a cryptic insertion of IGK and IGL enhancer regions near the CCND3 gene in three cases. Specific FISH probes detected 10 additional cryptic IGK juxtapositions to CCND3 (6 cases) and CCND2 (4 cases). In conclusion, virtually all CCND1-/SOX11+ MCL carry CCND2/CCND3 rearrangement with IG genes, including cryptic IGK/L enhancer regions not detected with currently used FISH probes.
