The actual benefits from pharmacogenetic testing for Warfarin metabolism are swamped by all the other factors which affect Warfarin metabolism (eg diet and other meds).
The FDA disagrees, and so does the evidence. And there are a whole lot of areas where pharmacogenetics is starting to have an impact on treatment. In any case, pharmacogenetics is a subset of pharmacogenomics; for example, as I mentioned in another comment, the lab where I work is working on expression-based tests for prediction of altitude sickness and setting up drug trials.
