The SYT Breakapart probe consists of a green 151kb probe and a red 148kb probe, which are positioned on each side of the SYT gene.
Synovial sarcomas account for up to 10% of soft-tissue sarcomas, typically arising in the para-articular regions in adolescent and young adults1.
A characteristic SYT(SS18)-SSX fusion gene resulting from the chromosomal translocation t(X;18)(p11;q11.2) is detectable in more than 90% of synovial sarcomas2, suggesting this is the primary causal event. The translocation fuses the SYT gene from chromosome 18q11.2 to either of two highly homologous genes at Xp11: SSX1 (Synovial Sarcoma X Breakpoint 1) or SSX2. In less than 1% of cases, SYT will be fused to a third gene, SSX43. SYT-SSX1 and SYT-SSX2 are thought to disrupt transcription and the subsequent expression of specific target genes4,5.
The quality and reproducibility of results using the CytoCell kit has been vital in accurately detecting co-deletions in our glioma investigations. We now have a cost-effective test that we can rely on that is also easy to use and interpret. We've been consistently impressed with this kit - not to mention the support offered by OGT's customer service, and have completely transitioned over to CytoCell probes.
