Google DeepMind Launches AlphaGenome Atlas, Mapping 9 Billion DNA Variants
Kansas City, Mo. – September 12, 2026 -- Google DeepMind has released AlphaGenome Atlas, a one-petabyte AI resource containing molecular-effect predictions for more than 9 billion possible single-letter DNA changes across the human genome, giving researchers browser-based access to the largest catalogue of its kind without writing code.
Atlas condenses billions of genetic variants into a single searchable score
The human genome's approximately 3 billion DNA letters create over 9 billion possible single-letter substitutions, a scale impossible to test experimentally in a lab. AlphaGenome Atlas assigns each variant thousands of molecular-effect predictions across hundreds of human cell types and tissues, feeding into a new AlphaGenome Variant Impact (AVI) score that combines AlphaGenome, AlphaMissense and evolutionary conservation data to rank variants across both protein-coding and non-coding regions.
