Google DeepMind Unveils AlphaGenome Atlas: A 1-Petabyte Map of 9 Billion Human DNA Variants

Google DeepMind has released AlphaGenome Atlas, a 1-petabyte AI-powered database containing computational predictions for all 9 billion possible single-letter DNA changes in the human genome, enabling researchers to rapidly identify disease-causing genetic variants that were previously undetectable. The atlas, published in Nature and unveiled in September 2026, integrates predictions from AlphaGenome and AlphaMissense into a unified variant impact (AVI) scoring system that analyzes non-coding regions—the 98 percent of the genome that does not encode proteins but harbors the majority of disease-associated variants.
