• Define precision medicine
• Recap the state of affairs of precision medicine initiatives
• To identify ways in which precision medicine may influence
clinical practice through a case-based example, specifically
focusing on:
• Pharmacogenomics
• Motivating behavioral changes
• To acknowledge the challenges and limitations of these
initiatives
