## TL;DR

SLC14A1 (Urea transporter 1) is a gene. In the public catalogues the evidence so far is association rather than a proven role.

## Summary

Mediates the transport of urea driven by a concentration gradient across the cell membrane of erythrocytes. Also mediates the transport of urea across the cell membrane of the renal inner medullary collecting duct which is critical to the urinary concentrating mechanism. Facilitates water transport in erythrocytes.

Open Targets scores its association with cancer at 0.51 (direct and indirect evidence; datatypes literature 0.87, animal model 0.29, genetic association 0.63).

## 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.
