Help: Chemical–Disease Associations


  1. Overview
  2. References


Chemical–disease associations may be inferred via curated chemical–gene and gene–disease associations. CTD contains curated and inferred chemical–disease associations.

Curated associations are extracted from the published literature by CTD curators.

Inferred associations are established via curated chemical–gene interactions (e.g., chemical A is associated with disease B because chemical A has a curated interaction with gene C, and gene C has a curated association with disease B).


Curated and inferred associations are identified, and help users develop hypotheses about mechanisms underlying environmental diseases. References provide details about the associations.
