## TL;DR

SSX1 (SSX family member 1) is a protein that switches other genes on and off. The public catalogues list it as a fusion partner, and the evidence so far is association rather than a proven role. Tied to Sarcomas and Synovial sarcoma.

## Summary

Could act as a modulator of transcription. Plays a role in spermatogenesis.

Open Targets scores its association with cancer at 0.69 (direct and indirect evidence; datatypes literature 0.70, genetic association 0.56, somatic mutation 0.98).

## Notes

- Written by scripts/fetch-cancer-genes.ts from CIViC, Open Targets, IntOGen, HGNC and UniProt; the function text is UniProt's, condensed and in UK spelling. Roles: UniProt disease notes describe a translocation or gene fusion involving the gene. Evidence tier "association-only" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
