The article introduces AlphaGenome, a novel AI tool designed to enhance the prediction of regulatory variant effects in human DNA. Unlike previous models, AlphaGenome can analyze DNA sequences of up to one million letters with high resolution, facilitating insights into gene regulation and disease biology. Its architecture combines convolutional layers for pattern detection and transformers for information communication across sequences, allowing it to predict a variety of molecular properties efficiently.
AlphaGenome’s capabilities include scoring the impact of genetic variants, modeling splice junctions directly from sequence data, and achieving state-of-the-art performance across genomic prediction benchmarks. While it has limitations—such as addressing distant regulatory elements and personal genome predictions—the model aims to accelerate research in understanding diseases, particularly in rare variants linked to disorders. Currently available via an API for non-commercial use, AlphaGenome represents a significant advancement in genomics, promising to deepen our understanding of genetic influences and facilitate new discoveries in healthcare and biology.
