DeepMind maps 9 billion DNA letter changes

Google DeepMind launched AlphaGenome Atlas on September 8, 2026, a roughly 1-petabyte catalogue of predicted molecular effects for about 9 billion single-nucleotide variants, covering every possible single-letter change in the human genome. The resource includes an AlphaGenome Variant Impact score that combines AlphaGenome and AlphaMissense predictions, and is free for academic use via a web portal and API, with commercial access planned on Google Cloud. DeepMind said collaborators have already used the atlas on unsolved rare-disease cases and UK Biobank trait studies.
