Mendelian Randomization an Approach for Precision and Public Health

Mendelian randomization is an approach that has the potential to contribute significantly to both precision medicine and public health. This approach uses genetic information to investigate the causal relationships between risk factors, such as lifestyle or environmental exposures, and disease outcomes.

Mendelian randomization relies on the concept of genetic variants that are randomly allocated at birth and act as instrumental variables for the exposure of interest. By using these genetic variants as proxies for the exposure, researchers can infer causality with greater confidence than traditional observational studies. In the context of precision medicine, Mendelian randomization can help identify novel drug targets and inform treatment decisions.

For example, if a genetic variant associated with low levels of LDL cholesterol is also associated with a lower risk of heart disease, this suggests that lowering LDL cholesterol through medication may be an effective way to prevent heart disease. Similarly, if a genetic variant associated with a particular cancer subtype is also associated with a specific drug response, this could inform treatment decisions for patients with that subtype of cancer.

In public health, Mendelian randomization can help identify modifiable risk factors for disease and guide interventions to reduce disease burden. For instance, if a genetic variant associated with a lower risk of type 2 diabetes, this could inform public health campaigns to promote physical activity as a way to prevent diabetes.

Mendelian randomization can also help disentangle the complex interplay between different risk factors, which is particularly relevant in multifactorial diseases such as cardiovascular disease, diabetes, and cancer.

Overall, mendelian randomization has the potential to contribute to the development of more personalized and effective treatments and interventions, as well as to the prevention of disease in the general population.
