Genomic Data Access and Management Service explained

GDAM is an API-based service run by Genomics England. It allows authorised users to access Whole Genome Sequencing (WGS) data and genomic test results for patients in the NHS GMS.

To ensure interoperability and scalability, GDAM follows two key international standards:

• FHIR (Fast Healthcare Interoperability Resources), a widely used healthcare data standard.
• GA4GH (Global Alliance for Genomics and Health) for ensuring compatibility with global genomic data-sharing initiatives.

GDAM offers flexibility for integrating genomic data and test results into existing NHS applications, enabling better data accessibility and analysis.

GDAM is built for:

• Bioinformaticians and clinical scientists who work with genomic data in the NHS.
• Healthcare IT professionals developing applications for NHS services.

Access is available where there is a legal basis to do so.

GDAM provides a series of API endpoints and a Python Client Library to simplify API integration.  

It doesn’t provide a graphical user interface (GUI).

Read the Genomic Data Access and Management API specification for details on:  API endpoints, data formats, authentication and usage examples.

To access this service, you need to complete the registration form to obtain an NHS API platform developer account.
