## TL;DR

MSMB (Beta-microseminoprotein) is a gene. In the public catalogues the evidence so far is association rather than a proven role. Tied to Prostate cancer.

## Summary

UniProt has no function text for P08118; HGNC names it "microseminoprotein beta".

Open Targets scores its association with cancer at 0.63 (direct and indirect evidence; datatypes literature 0.93, animal model 0.30, genetic association 0.69, genetic literature 0.61).

## 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: none stated by the sources. Evidence tier "association-only" is the strongest of those signals.
- Prevalence not recorded: none of the sources gives a positivity rate.
