If it were not for the great variability among individuals, medicine might as well be a science and not an art. Sir William Osler's observations in 189260 reflect a perception of medicine over 100 years ago, highlighting the lack of available objective data to make decisions that are tailored to individual patients. One hundred years later, scientists are on the verge of being able to identify inherited differences between individuals, which may predict each patient's response to a particular drug. This ability will have undoubted benefits in the discovery, development, and delivery of new medicines. Sir William Osler, if he were alive today, would be forced to reconsider his view of medicine as an art not a science.
Pharmacogenetics emerged as a discipline that attempted to understand the hereditary basis for differences in responsiveness or inter-individual variation to therapeutic agents.85 Variation in a drug effect may vary from
