Genomics and Precision Health Topics

Genomics and family health history play a role in many diseases such as cancer and heart disease. These diseases are partly the result of how your genes interact with your behaviors, such as your diet and physical activity, the environment, and other social factors. The following information pages provide the latest information on common diseases and other health related topics developed by our office and other CDC programs.  For more information on genomics and precision health, search our Public Health Genomics and Precision Health Knowledge Base for continuously updated information on specific diseases and health topics.

Polygenic risk scores for a disease for different people in a population. Each circle represents a person. Those with higher scores (red) are more likely to get the disease and those with lower scores (yellow) are less likely to get the disease. Most people will fall somewhere in the middle (orange).
