About 100 guests from 36 countries met on the XVIII. MetaSystems Distributor Meeting (DM) in November to exchange experiences and to get to know new trends and developments at MetaSystems.

- 100 µl (10 Tests)
XL t(6;14) CCND3/IGH DF consists of an orange-labeled probe hybridizing to the CCND3 gene region at 6p21.1 and a green-labeled probe hybridizing to the IGH gene region at 14q32.3.
Probe maps are created in accordance with the intended purpose of the product. Solid colored bars do not necessarily indicate that the probe fully covers the indicated genomic region. Therefore, caution is advised when interpreting results generated through off-label use. Probe map details based on UCSC Genome Browser GRCh37/hg19. Map components not to scale. Further information is available on request.
The most frequent primary abnormalities in multiple myeloma (MM) are trisomies of odd-numbered chromosomes or translocations involving the immunglobulin heavy chain (IGH) gene locus. The most common MM-associated IGH translocations are t(11;14), t(4;14), t(6;14), t(14;16) and t(14;20) in the order of their occurrence. The consequence of these rearrangements is the dysregulation of genes juxtaposed to transcriptional enhancers in the IGH locus. Prognosis and risk stratification strongly depend on the detection and interpretation of cytogenetic primary abnormalities. t(14;16) and t(14;20) are considered as high risk, t(4;14) as intermediate risk and t(6;14) and t(11;14) as standard risk cytogenetic aberrations in patients with MM based on FISH testing. Secondary aberrations are also influencing the outcome.
Cyclins of the D-family are essential for the transition from G1- to S-Phase during the cell cycle. t(6;14)(p21;q32) moves the cyclin D3 gene in proximity to 3´ IGH enhancer sequences and is associated with cyclin D3 overexpression. The chromosomal translocation has been reported as a rare and recurrent event not only in myeloma but also in other B-cell malignancies such as diffuse large B-cell lymphoma.
- Multiple Myeloma and Plasma Cell Neoplasms (MM)
Two green (2G) and two orange (2O) signals.
Aberrant Cell (typical results):
One green (1G), one orange (1O), and two green-orange colocalization/fusion signals (2GO) resulting from a reciprocal translocation between the relevant loci.
