The IGH/MYEOV product consists of probes, labelled in green, covering the Constant and Variable segments of the IGH gene, and MYEOV probes, labelled in red. The MYEOV probe mix contains a 155kb probe centromeric to the MYEOV gene, which includes the TPCN2 gene and a second probe, telomeric to the MYEOV gene, covering the 162kb region including the CCND1 and ORAOV1 genes.
The MYEOV (myeloma overexpressed) gene is located at 11q13.3 and IGH (immunoglobulin heavy locus) at 14q32.33.
Approximately 50-60% of multiple myeloma (MM) cases are associated with translocations involving IGH and one of several partners including CCND1, NSD2 (WHSC1) and FGFR3, CCND3, MAF or MAFB1.
The t(11;14)(q13;q32) translocation is the most common translocation in MM, where it is seen in approximately 15% of cases2,3.
Unlike mantle cell lymphoma (MCL), where the breakpoints are clustered in a 1kb region that is 120kb centromeric to the CCND1 gene4, the breakpoints in MM cases are dispersed within a 360kb region between CCND1 and MYEOV at 11q135. MYEOV is a putative oncogene, located 360kb centromeric to CCND1, which is thought to be activated in the translocation by becoming closely associated with IGH enhancers. In contrast to IGH rearrangements in other neoplasms, those found in MM have IGH breakpoints predominantly in the C/J region, which, in the case of MYEOV, brings the MYEOV gene under the control of the 3' Eα1 enhancer5. In CCND1 translocations by contrast, the Eμ enhancer controls CCND1 expression. MYEOV overexpression is a possible prognostic factor in MM6.
The t(11;14)(q13;q32) associated with a favourable outcome in most series and therefore is regarded as neutral with regard to prognosis3.

Find certificate of analysis documentation for our CytoCell FISH probes
Our lab has been using a wide range of CytoCell FISH probes for a number of years, and have been increasing this range all the time. The probes have clear bright signals and show good reproducibility. CytoCell provides fast delivery of catalogue probes, and are very responsive when we have any queries or problems with their products.

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. OGT's customer support is outstanding, as their staff are extremely knowledgeable and truly care about their customers and their customers’ needs.

Director of Cytogenetics, Carolinas Pathology Group, USA
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.

We have been working with CytoCell fish probes for two decades because of their excellent clarity and intensity regardless of the size of the probe. It is so clear and simple to detect.

The quality and consistency of CytoCell’s probes means I can trust the results, and my clients get their results in a timely manner.
Dr. Theresa C. Brown
Director, Cytogenetics Laboratory, Hayward Genetics Center, Tulane University School of Medicine, USA
It was very important for us to have more consistent results with our probes — easy-to-read bright signals and a range of vial sizes, which is much more cost-effective.
Janet Cowan, PhD
Director of the Cytogenetics Laboratory, Tufts Medical Center, USA
Not only do CytoCell offer an extensive range of high-quality FISH probes, the customer support is also excellent — providing fast access to all the probes I need. The probes are highly consistent with bright signals allowing easy scoring of results.
Dr. Eric Crawford
Senior Director, Genetics Associates Inc., USA
The quality and reproducibility of results using the CytoCell kit has been vital in accurately detecting co-deletions in our glioma investigations. We now have a cost-effective test that we can rely on that is also easy to use and interpret. We've been consistently impressed with this kit - not to mention the support offered by OGT's customer service, and have completely transitioned over to CytoCell probes.
