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.
The t(11;14)(q13;q32) translocation involving CCND1 (cyclin D1) gene at 11q13.3 and the IGH (immunoglobulin heavy locus) gene at 14q32.33 is associated with mantle cell lymphoma.
The t(11;14)(q13;q32) rearrangement involving CCND1 and IGH is considered the hallmark of mantle cell lymphoma (MCL)1, the presence of which can be used to aid in the differential diagnosis of CD5+ B-cell lymphoproliferative disorders2.
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.
