Along with the rapid progress in the field of
human genomics,
genome-wide association studies have successfully identified numerous
risk loci for complex
diseases.
Polygenic risk scores can predict
disease risk by integrating the effects of multiple susceptibility loci, and begin to show good performance for improving
risk prediction,
screening strategy and precision prevention. This
paper briefly reviews the recent progress of
polygenic risk scores in
disease prevention, and summarizes the opportunities and challenges of its application.
