Summary
Identifying genetic markers can help tailor blood pressure (BP) medications. However, most BP response variations remain unexplained, necessitating whole-genome studies for personalized hypertension treatment.
Area of Science:
- Pharmacogenomics
- Cardiovascular Genetics
- Molecular Medicine
Background:
- Genetic variation influences individual responses to antihypertensive drugs.
- Hypertension management can be improved by identifying genetic predictors of drug response and target-organ complications.
Purpose of the Study:
- To review recent genetic markers that predict interindividual differences in response to antihypertensive medications.
- To highlight the need for advanced genetic approaches to optimize hypertension therapy.
Main Methods:
- Review of recently reported polymorphisms associated with blood pressure (BP) response.
- Discussion of current limitations in predicting drug response based on single-gene variations.
Main Results:
- Single-site genetic variations explain only a small portion of BP response differences.
- Most variation in drug response remains unexplained by known genetic and environmental factors.
Conclusions:
- Whole-genome approaches are needed to discover novel genetic pathways influencing drug response.
- Larger sample sizes and consideration of gene-gene and gene-environment interactions are crucial for personalized hypertension therapy.
