The yearly MetaSystems Distributor Meeting (DM), brought into life in 2002 as a platform to gather all international partners of MetaSystems and other members of the global MetaSystems family, just ended last week. The DM is being organized in turns by MetaSystems Headquarters, MetaSystems USA (MGI), and MetaSystems Asia. Since MGI is celebrating its 25th anniversary in 2018 they decided to choose a special location: Nassau, The Bahamas!

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.

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 respective locus.
