How were the sample providers identified to contribute samples to the project?

The sample providers for the GenCoE-PAGRA African WGS Moonshot Project were identified primarily from H3Africa researchers and African investigators who had previously contributed biological samples for genomic studies. Samples were selected based on existing consent agreements, ensuring that data sharing and secondary use were permitted without restrictions on pharmaceutical applications. Additionally, providers with ongoing sample collection efforts could contribute if their samples reached sequencing facilities within the project's timeframe. The selection process emphasized diverse representation of African genomic data while maintaining ethical standards and participant anonymity.
