XL t(11;14) MYEOV/IGH DF

XL t(11;14) MYEOV/IGH DF consists of an orange-labeled probe hybridizing to the MYEOV/CCND1 gene region at 11q13.3 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.

Clinical Details

Mantle cell lymphoma (MCL) is a B-cell non-Hodgkin lymphoma (NHL) with an aggressive clinical course. It is genetically characterized by t(11;14)(q13;q32) which is present in about 95% of MCL patients. By lower frequency, t(11;14) is also detectable in B-cell prolymphocytic leukemia, myelomas and chronic lymphocytic leukemia. The translocation induces overexpression of CCND1 which is normally not detected in B lymphocytes. CCND1 is a major player in cell cycle regulation and involved in the G1/S-phase transition. The oncogenic potential of CCND1 overexpression is related to its role in the cell cycle but also to other, non-cell cycle-related mechanisms such as increased genomic instability and cell survival. t(11;14) is considered as a primary event, often followed by secondary chromosome alterations.
In multiple myeloma (MM), t(11;14) is the most common translocation, detectable by FISH in about 15-20% of all MM patients. Conventional cytogenetics has a much lower sensitivity, detecting t(11;14) in about 5% of MM patients. MM t(11;14) patients do have a relatively favorable outcome compared to other recurrent IGH translocations.

Clinical Applications

Expected Patterns

Expected Pattern 1

Normal Cell:
Two green (2G) and two orange (2O) signals.
