Artificial intelligence is giving scientists powerful new ways to understand the human genome, helping turn billions of DNA letters into information that could improve our understanding of health and disease. AI and machine-learning systems can search genomic datasets for patterns that would be difficult for humans to recognize, helping researchers distinguish potentially disease-causing genetic variants from harmless ones, investigate cancer, and improve gene-editing technologies such as CRISPR.
In the future, AI models could become better at predicting how changes in DNA affect cells and organs, connecting genomic information with medical records, proteins, environmental factors, and other biological data to help scientists understand why diseases develop and identify possible treatments. These capabilities could contribute to precision medicine, in which prevention and treatment are increasingly tailored to the biology of an individual patient rather than relying entirely on a one-size-fits-all approach.
However, combining AI with human genomic information also raises important concerns about privacy, data security, bias, and equitable representation, particularly because genetic information is uniquely personal and difficult to make truly anonymous. The National Institutes of Health has specifically warned that generative AI models trained on controlled human genomic data could potentially expose sensitive information, making strong safeguards essential as the technology advances. Ultimately, the combination of AI and genomics could help us move from simply reading the human genome toward understanding what its enormous amount of information actually means.
