We call evidence a unit of data that support a connection between a target and a disease. The Open Targets Platform integrates multiple types of evidence including genetic associations, somatic mutations, RNA expression and target-disease associations mined from the literature. This method allows you to retrieve a single evidence item or a list of pieces of evidence by using their targetvalidation.org ID.
Evidence IDs are unique within each data release (e.g. 8ed3d7568a8c6cac9c95cfb869bac762 for release 1.2).
You can obtain a list of evidence and their IDs from other API calls such as .
Please note that a specific evidence ID may change between data releases. We can not guarantee that a specific evidence ID will refer to the same piece of evidence connecting a target and its diseases.
