A Pharmacogenetic Drug-Gene Target Would Be Most Successful When Clinically

A pharmacogenetic drug-gene target would be most successful when clinically implemented when it:

A) is associated with a clinically significant effect on the relationship between drug dose and plasma concentration.
B) does not involve a major metabolic pathway but instead is involved in alternate pathways.
C) indicates alternative drugs that are much more efficient than conventional drugs in producing a dose-response.
D) allows for an extended period of time for changes to be made in drug dosing.
