## TL;DR

FAM131B (family with sequence similarity 131 member B) is a gene. In the public catalogues the evidence so far is association rather than a proven role.

## Summary

UniProt has no function text for Q86XD5; HGNC names it "family with sequence similarity 131 member B".

Open Targets scores its association with cancer at 0.62 (direct and indirect evidence; datatypes literature 0.12, affected pathway 0.89, genetic association 0.00, somatic mutation 0.49).

## 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.
