IGH/CCND1 Plus Translocation, Dual Fusion
- CCND1, 11q13.3, Red
- IGH, 14q32.33, Green
The IGH/CCND1 Plus product consists of probes, labelled in green, proximal to the Constant, and within the Variable segment of the IGH region and CCND1 probes, labelled in red. The CCND1 probe mix contains a 155kb probe centromeric to CCND1 gene, covering a region between the D11S2663 and the D11S4095 markers, and a second probe (162kb) covering the telomeric end of CCND1 gene and the region up to FGF3 gene.
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 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.
I first came across Cytocell FISH probes in a previous lab I worked in and I was struck by the quality of the products. Since this time, I have been recommending and introducing Cytocell probes across all application areas — now they are the primary FISH probes used in our lab. They have an excellent range of products and their ready-to-use reagent format saves considerable time. As a matter of fact, at a recent conference there was a discussion about the lack of commercial probes for a particular disorder and I was happy to point the participants in the direction of the Cytocell catalogue, which contains the exact probes required.
