Slide 2: Introduction to Pharmacogenetics
Title: Introduction
Content:
Definition: Pharmacogenetics focuses on how genetic variations affect individual drug
responses.
Goal: Tailor drug therapy to genetic profiles for optimized efficacy and reduced adverse
effects.
Impact: Revolutionizes clinical practice, ensuring safe and effective treatment.
Example: CYP2C9 and VKORC1 genetic variants influencing warfarin dosing (Wang et
al., 2024).

Slide 4: Genetic Testing Techniques
Title: Genetic Testing Techniques
Content:
Sanger Sequencing:
Description: Gold standard for detecting specific genetic variants.
Advantages: High accuracy.
Limitations: Low throughput; not ideal for large-scale studies (Jorgenson et al., 2009).
Polymerase Chain Reaction (PCR):
Description: Amplifies specific DNA sequences.
Application: Detects genetic polymorphisms using techniques like PCR-RFLP (Caudle et
al., 2023).
Slide 5: Advanced Genetic Testing
Title: Advanced Genetic Testing Techniques
Content:
Next-Generation Sequencing (NGS):
Impact: Enables simultaneous sequencing of multiple genes.
Applications: Comprehensive profiling for diverse populations.
Example: Identifying variants in CYP450 genes (Eugenomic, n.d.).
Microarray Technology:
Capability: Genotypes thousands of SNPs at once.
Use Case: Essential for GWAS to link genetic variants with drug responses (TGA
Australia, 2024).
Slide 6: Analytical Approaches
Title: Analytical Approaches
Content:
Genome-Wide Association Studies (GWAS):
Purpose: Identify associations between genetic variants and drug responses.
Output: Insights into specific alleles influencing outcomes (Swen et al., 2019).
Haplotype Analysis:
Focus: Impact of allele combinations on drug metabolism.
Example: Haplotypes in CYP2D6 influencing antidepressant efficacy.
Gene-Environment Interaction Studies:
Description: Examines interplay between genetics and environmental factors.
Example: Smoking affecting CYP1A2 activity and caffeine metabolism (Wang et al., 2024).
Slide 7: Clinical Implementation
Title: Clinical Implementation
Content:
Key Steps:
Evidence Evaluation: Identify actionable drug-gene pairs (Caudle et al., 2023).
Genotyping Strategy: Collaborate with molecular labs for method selection.
Data Interpretation: Leverage clinical decision support systems for tailored treatments.
Example:** Pharmacogenetic testing for clopidogrel efficacy based on
CYP2C19 genotype.
Slide 8: Challenges in Pharmacogenetics
Title: Challenges
Content:
Standardization Issues: Variability in testing methods across labs (Swen et al., 2019).
Clinical Utility: Difficulty in establishing the significance of identified variants.
Ethical Concerns: Consent, privacy, and genetic discrimination risks (The Pharmaceutical
Journal, n.d.).
Economic Barriers: Limited accessibility in low-resource settings, including sub-Saharan
Africa (Ogundele et al., 2021).
Slide 9: Conclusion
Title: Conclusion
Content:
Pharmacogenetics enhances personalized medicine by tailoring drug therapies.
Future Needs:
Standardization and guidelines.
Broader inclusion in genetic studies.
Collaboration among stakeholders.
Vision: Integrating AI and advanced analytics to drive progress.
