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), were frequently 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 MCL. The IGH/CCND1 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.
In our hands, Cytocell FISH probes, have proven to be of the highest quality with bright, easy to interpret signals, thus providing confidence in our results. Cytocell’s customer support is outstanding, as their staff are extremely knowledgeable and truly care about their customers and their customers’ needs.
