IGH/MYEOV Translocation, Dual Fusion
- MYEOV, 11q13.3, Red
- IGH, 14q32.33, Green
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 most common translocation in Multiple Myeloma (MM) is the t(11;14)(q13;q32)1, which accounts for 15-20% of cases as identified by FISH2.
Unlike Mantle Cell Lymphoma (MCL), where the breakpoints are clustered in a 1kb region that is 120kb centromeric to the CCND1 gene3, the breakpoints in Multiple Myeloma cases are dispersed within a 360kb region between CCND1 and MYEOV (MYEloma OVerexpressed) in band 11q134.
MYEOV is a putative oncogene, located 360kb away from 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 Multiple Myeloma 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 enhancer4. In CCND1 translocations by contrast, the Eµ enhancer controls CCND1 expression.MYEOV overexpression is a possible prognostic factor in MM5.
I am grateful for the excellent products I receive from Cytocell at a reasonable price, but more importantly the superb customer support. The speed in which I receive answers or suggestions makes my life as a director much easier and allows me to focus on patient care. 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
