The text states that virtually every therapeutic area involving medication use includes a drug for which documented genetic variability has the potential to affect what?

For some agents, dosing recommendations based on an individual's genetic information are also called what?

What is the consequence if a drug that is an active parent drug is given to a patient who has a genetic variant resulting in an inactive metabolizing enzyme responsible for its breakdown?

What is an efflux transporter protein in the context of pharmacogenomics?

In addition to individual genes, pharmacogenomics increasingly examines the role of what in relation to drug therapy outcomes?
