IGH/CCND1 Translocation, Dual Fusion
Although translocations involving IGH and CCND1 (BCL1) were initially reported in B-CLL patients, the rearrangement is now considered to be a hallmark of mantle cell lymphoma (MCL).
Reciprocal translocations involving the IGH and CCND1 (previously known as BCL1) loci, t(11;14)(q13;q32), have been reported in B-CLL patients1. The involvement of the CCND1 (Cyclin D1) gene was initially reported from a cloning study looking at the breakpoints of the translocation. However, it is likely that the initial diagnosis on the samples used for the study should have been mantle cell lymphoma (MCL). The CCND1/IGH probe for detection of t(11;14) has been recommended by the British Committee for Standards in Haematology to enable atypical B-CLL patients to be distinguished from possible MCL patients2.
