NOTE: LDH is an API service. The API was originally developed in support of ClinGen. This legacy UI was used to ease illustration, demonstration, and explanation of its approach and content.
- It is not the primary application or interface, which is the API itself
- This UI is no longer maintained and in some sense a distraction.
- Therefore, this UI is deprecated and slated for removal.

Linking data entities from different sources
The ClinGen Linked Data Hub (LDH) facilitates efficient access to collated information such as links and select data from different data sources, which are made available using RESTful APIs. Currently, LDH focuses on linking information about human genes and variants to support ClinGen curation efforts. Learn more

Contribute data and links to LDH

- Do you have links to supporting evidence which will be useful for variant interpretation or gene validity or clinical actionability?
- Do you have data that is not available in any other web-accessible data source and would you like to embed such data within LDH?
LDH content and access

- Are you looking for a single source of information for your curation efforts?
- Do you want to learn about the different kinds of entities stored in LDH?
- Do you want to explore ways to access content in LDH?
