XL DDIT3 BA consists of an orange-labeled probe hybridizing proximal to the DDIT3 gene region at 12q13.3 and a green-labeled probe hybridizing distal to the DDIT3 gene region at 12q13.3-14.
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.
Histological similarities and a subset of common immunohistochemical features make the diagnosis of soft tissue neoplasms challenging. Several entities characterizing reciprocal translocations have been identified and FISH based assays specific for the detection of these aberrations have become a valuable tool in diagnostics today. Myxoid/round cell liposarcoma (MRCLS) is the most common liposarcoma with an increased incidence in the extremities. Compared to other liposarcomas, MRCLS has a greater tendency for metastasis. It is characterized by the reciprocal translocation t(12;16)(q13;p11) which is present in up to 95% of cases. The resulting FUS-DDIT3 fusion protein has oncogenic potential and interferes with adipogenic differentiation. A paralog of FUS with high sequence homology is the EWS RNA Binding Protein 1 (EWSR1). EWSR1 is an alternative translocation partner of DDIT3 and the resulting fusion protein EWSR1-DDIT3, originating from t(12;22)(q13;q12), accounts for <5% of MRCLS cases. DDIT3 rearrangements are highly specific for MRCLS due to the presence of FUS-DDIT3 or EWSR1-DDIT3 fusion genes.
Normal Cell:
Two green-orange colocalization/fusion signals (2GO).
Aberrant Cell (typical results):
One green-orange colocalization/fusion signal (1GO), one separate green (1G) and orange (1O) signal each resulting from a chromosome break in the relevant locus.
