China releases powerful DNA-screening AI tool for free to help fight rare diseases

Chinese researchers have launched OneGenome, a powerful open-source AI tool aimed at accelerating the diagnosis of rare genetic diseases, a process often described as a grueling "diagnostic odyssey" for patients.

Rare diseases, predominantly genetic, can leave patients and their families searching for answers for years. They often visit multiple specialists and undergo inconclusive tests, with the root cause hidden within the complex three billion base pairs of human DNA. OneGenome emerges as a potential solution to shorten this arduous journey.

The AI system is designed to bridge the gap between raw DNA sequences and the world's extensive clinical literature, helping to formulate treatment approaches. Unlike models that merely read DNA sequences, OneGenome is trained to reason, applying accumulated human medical logic to interpret the clinical consequences of gene mutations.

Developed by BGI-Research, OneGenome integrates Genos, a genomic foundational model trained on diverse global populations, with large language model capabilities. Early tests indicate that OneGenome has outperformed general large language models like DeepSeek-v4 and other traditional gene models in multiple clinical diagnostic and medication guidance assessments.
