Summary
Genetic markers for common adult diseases are increasingly used for diagnosis and treatment. However, complex gene interactions complicate their application compared to single-gene disorders, necessitating careful consideration of potential misapplications.
Area of Science:
- Genetics
- Medicine
- Disease Prediction
Background:
- Over 15 years, numerous genetic markers for multifactorial adult diseases have been identified.
- Examples include Factor V Leiden for venous-thromboembolism, LPL mutations for hypertriglyceridemia, and APOE4 for Alzheimer's disease.
Purpose of the Study:
- To discuss the emerging use of genetic markers in adult multifactorial diseases.
- To highlight the complexities and potential misapplications of these markers.
Main Methods:
- Review of identified genetic markers for common multifactorial diseases.
- Comparison of genetic marker complexity in multifactorial versus monogenic disorders.
Main Results:
- Genetic markers are being integrated into clinical practice for diagnosis, prognosis, and therapy targeting.
- Gene-gene and gene-environment interactions significantly increase the complexity of using these markers.
Conclusions:
- The application of genetic markers for multifactorial diseases is more intricate than for monogenic disorders.
- Potential misapplications warrant careful consideration and further research.
