Frequently Asked Questions

How do I find chemical–disease relationships?

CTD contains curated and inferred chemical--disease relationships. Curated chemical–disease relationships are extracted from the published literature by CTD curators. Inferred relationships are established via CTD-curated chemical–gene interactions: chemical A directly interacts with gene B and gene B is associated with disease C, so chemical A has an inferred relationship with disease C (via gene B).

Curated and inferred relationships are identified as such, and help you develop hypotheses about mechanisms underlying environmental diseases.

Open the chemical page for a chemical of interest by performing a chemical keyword search. Click on the Diseases tab to view the diseases associated with the chemical or any of its descendants.
