'Polygenic risk scores' total hundreds or thousands of genetic factors to predict your risk of disease. A new study validates scores for AFib, diabetes, breast cancer, and more.
The scores were tested among 227 healthy adult patients. Of those, 11% had a high-risk score for atrial fibrillation, 7% for coronary artery disease, 8% for diabetes, and 6% for colorectal cancer. Among men, 15% had a high score for prostate cancer, while 13% of women had a high score for breast cancer.
