Hi all,

Thank you for joining us for the "GA4GH in Real world " session at the GA4GH October Connect meeting 2025!

We've updated the agenda document with the following key takeaways and next action items from the session.

Key takeaways:

 

1. Real-World Data Sharing: IPCHiP Case Study

  • The International Precision Child Health Partnership (IPCHiP) exemplifies borderless data sharing using GA4GH principles.
  • Key challenges include managing on-prem vs. cloud environments, ensuring data security, and providing metadata access.
  • Emphasis on transparency in both successes and setbacks when adopting GA4GH standards.

 

2. Federated Variant-Level Matching and Imputation Platform

  • A federated imputation platform, presented by Mamana, connects multiple imputation services through one interface, improving accuracy and efficiency.
  • Built using GA4GH standards, currently supporting Michigan imputation software and multiple reference panels.
  • Highlights the need for better integration between DRS and WES.
  • Discussions emphasized regional engagement (e.g., in Uganda and Kenya) and starting with small-scale implementations.

 

3. Pacific Analytics Toolkit and Cloud Components

  • Pacific Analytics demonstrated an open-source, framework-agnostic toolkit for building interoperable platforms using GA4GH standards.
  • The system supports data discovery, workflow execution, and repository integration.
  • Encourages collaboration across groups and integration of GA4GH standards with existing infrastructure.

 

4. Minimal Starter Kit for Interoperability

  • Proposal for a “minimal starter kit” to deploy real-world interoperable systems beyond demo environments.
  • Focuses on essential components: authentication, authorization, data models, APIs, storage, logging, and auditing.
  • The approach involves defining scientific use cases, aligning on relevant standards, and deploying public data demos with stakeholder input.

 

5. Federated Machine Learning (FML) and Community Collaboration

  • Federated ML discussed as a privacy-preserving alternative to centralized models.
  • Challenges include data preparation, access permissions, and authentication/authorization.
  • A new Cloud, ML, and AI Working Group formed to develop frameworks supporting federated ML across GA4GH standards.
  • Emphasis on community engagement and addressing legal, ethical, and security aspects in federated environments.

 

Next steps:


1.     Enhance Standards Integration

 

  • Improve interoperability between DRS, WES, and other GA4GH APIs to support federated analysis platforms.

 

2.     Advance the Minimal Starter Kit


  • Define scope, core components, and priority standards.
  • Develop and test a prototype deployment using public data.

3.    Expand Federated Compute and ML Initiatives

  • Continue work within the Cloud, ML, and AI group to define use cases and build a shared framework.
  • Ensure strong links with security, ethics, and governance workstreams.

4.     Promote Community Adoption

  • Organize regional workshops (e.g., in Africa) to raise awareness and support small-scale pilot implementations.
  • Foster collaboration among groups like Pacific Analytics and federated data initiatives.

5.    Document and Share Learnings

  • Publish case studies (e.g., IPCHiP, Federated Imputation) demonstrating real-world adoption of GA4GH standards.
  • Encourage sharing of implementation experiences — both challenges and successes — to build community confidence.
