Synovial sarcoma, X breakpoint

Synovial sarcoma, X breakpoint (SSX) refers to a group of genes rearranged in synovial sarcoma.[1]

They include:

The group also has several associated pseudogenes, and the interacting protein SSX2IP.

The translocation t(X;18) creates a fusion of the SYT gene(at 18q11) with either SSX1 or SSX2 (both at Xp11). Neither SYT, nor the SSX proteins contain DNA-binding domains. Instead, they appear to be transcriptional regulators whose actions are mediated primarily through protein-protein interactions, with BRM in the case of SYT, and with Polycomb group repressors in the case of SSX.
