Understanding genetic susceptibility is crucial for several reasons: 1. Risk Prediction: Identifying genetic risk factors can help predict an individual’s likelihood of developing a disease. 2. Targeted Prevention: High-risk individuals can be targeted for early interventions and preventive measures. 3. Personalized Medicine: Treatments can be tailored based on an individual’s genetic profile, improving efficacy and reducing adverse effects. 4. Public Health Strategies: Knowledge of genetic susceptibility can inform public health policies and resource allocation.
