DeepMind has launched a powerful new AI model, AlphaGenome, that promises to transform how scientists understand the human genome—especially the mysterious non-coding regions long dubbed DNA’s “dark matter.” The model can predict how single DNA variants affect gene regulation across the genome, enabling researchers to better link genetic mutations to diseases such as cancer.
A milestone in understanding gene regulation
AlphaGenome stands apart from earlier models like Enformer and AlphaMissense by targeting non-coding regions of DNA—areas that don’t directly encode proteins but regulate gene activity. These regions make up 98% of the human genome and are increasingly recognized as key to understanding complex diseases.
The AI model can analyze up to 1 million base pairs at once, delivering high-resolution predictions across thousands of molecular processes. This includes gene start-and-stop points, RNA splicing, and protein binding. By combining short-range pattern detection and long-range dependency tracking, AlphaGenome offers a unified view of genome functionality.
According to DeepMind, AlphaGenome outperformed external models in 22 out of 24 predictive benchmarks and matched or exceeded top performers in 24 out of 26 tasks related to genetic variant impact.
From leukaemia to broader genetic discovery
In one key demonstration, AlphaGenome accurately predicted how mutations involved in T-cell acute lymphoblastic leukaemia (T-ALL) activate the cancer-associated TAL1 gene by creating a new protein binding site. This shows the model’s ability to trace the disease-causing pathways of non-coding variants—an area that has long posed challenges for genomic research.

Experts see broad potential. Dr. Caleb Lareau of Memorial Sloan Kettering called AlphaGenome a milestone, while Prof. Marc Mansour of University College London noted that it fills a critical gap in large-scale analysis of non-coding regions.
However, DeepMind cautioned that AlphaGenome is not yet validated for clinical use or personal genomic analysis. The model still struggles with interpreting long-range DNA interactions that exceed 100,000 base pairs.
Access and future potential
AlphaGenome is now available via API for non-commercial research, and DeepMind has opened collaboration through its community forum. The company sees the model accelerating discovery in genomics, synthetic biology, and healthcare.
“We hope AlphaGenome will deepen our understanding of the complex cellular processes encoded in the DNA sequence,” DeepMind said in a statement, “and drive exciting new discoveries.”
As AI tools increasingly complement biomedical science, AlphaGenome signals how AI might unlock answers hidden within our genetic code—redefining both basic biology and the future of precision medicine.
