The 1000 Genomes Project, reanalyzed: A new analytical baseline for human genomics
Public Sector Blog
This article announces a comprehensive reanalysis of the 1000 Genomes Project using Illumina DRAGEN on AWS EC2, establishing a modern analytical baseline for human genomic variation.
- Reanalyzed 3,202 whole genomes across five DRAGEN versions (3.5–4.4) using EC2 F2 instances
- DRAGEN v4.4 detects SNVs, indels, CNVs, structural variants, STRs, and HLA types in a single integrated pipeline
- Pangenome reference reduces reference bias for non-European populations compared to linear reference alignment
- Full WGS analysis 2x faster and 30% cheaper than previous-generation F1 instances
- Dataset freely accessible via Registry of Open Data on AWS with no egress fees
- Includes Jupyter notebooks for exploratory analysis and open-source conversational agent using Amazon Bedrock for natural-language queries
This reanalysis removes analytical limitations of the original 1000 Genomes Project calls, enabling researchers to validate new methods and conduct population-scale genomics research with current detection capabilities.
