Lacy, there are several discussions about genetic testing on Mayo Clinic Connect. Here's a couple:
- Why Genetic Testing for Mental Health Meds is Important https://connect.mayoclinic.org/discussion/why-genetic-testing-for-mental-health-meds-is-important/
- Cytochrome P450 Drug Metabolization Polymorphisms https://connect.mayoclinic.org/discussion/cytochrome-p450-drug-metabolization-polymorphisms/

There are others related to genetic testing and pharmacogenetics and cancer or heart disease and other conditions.
