Genetic data is used in epidemiology to: - Identify populations at risk: By understanding genetic predispositions, researchers can identify individuals or groups who are at higher risk for specific diseases. - Develop personalized medicine: Genetic insights can guide the development of personalized treatment plans tailored to an individual’s genetic makeup. - Understand disease mechanisms: Studying genetic factors helps in understanding the biological mechanisms underlying diseases, which can lead to the development of new therapeutic interventions.
