University Of Florida Researchers Develop AI Tool To Address Ancestral Bias In Genetic Data For Precision Medicine

A team of researchers at the University of Florida, led by Kiley Graim, Ph.D., has developed PhyloFrame, an AI tool designed to address ancestral bias in genetic data, a critical issue limiting advancements in precision medicine. By integrating population genomics data from diverse ancestries, PhyloFrame enhances the accuracy and equity of predictive models, ensuring better treatment outcomes for underserved populations.

Funded by the National Institutes of Health and supported by UF’s AI2 Datathon grant, this innovation leverages supercomputers like HiPerGator to process extensive genomic datasets. Published in Nature Communications, PhyloFrame aims to revolutionize clinical settings by reducing model overfitting and improving early diagnosis and personalized treatments, ultimately striving for equitable healthcare solutions.

Addressing Ancestral Bias In Genetic Data

The team led by Kiley Graim has developed PhyloFrame, an AI tool designed to address ancestral bias in genetic data. This issue arises when most research relies on data primarily from European populations, limiting the effectiveness of precision medicine for other groups. PhyloFrame enhances model accuracy across diverse populations by integrating large population genomics databases with disease-specific datasets.

The importance of this work lies in the current models’ lack of global diversity representation. Most genetic data originates from European ancestry due to funding and socioeconomic factors, excluding underserved groups. This exclusion impacts treatment effectiveness. Interestingly, even European models benefit from more diverse data as it reduces overfitting, improving overall accuracy.

PhyloFrame’s development involved processing massive genomic datasets using UF’s HiPerGator supercomputer, a significant computational achievement. The team began with simple models and expanded their work with funding support, highlighting the tool’s potential for broader applications.

Graim envisions using PhyloFrame clinically to tailor treatments based on individual genetics. This could enhance diagnostics and personalized therapies, reduce side effects, and make precision medicine more equitable.
