These results suggest that Pro42, Arg377, and Arg456 are critical amino acids for the production of catalytically active CYP1A2 holoenzyme. Concept et réalisation C.G.R. Fig. Because CYP1A2 activity has been shown to vary up to 60-fold among patients, we proposed that a convenient measure of CYP1A2 activity, the [(13)C 3-methyl] caffeine breath test (CBT), might be clinically useful in identifying patients most susceptible to tacrine liver toxicity.

Utility of integrated pharmacogenomic testing to support the Inter-individual variation in drug response among patients is a major obstacle in medicine application, due to the different response of each patient to the same medication ().Several cases of adverse drug reactions occurring in certain patients, such as renal/hepatic disorders, congestive heart failure and anemia, were previously reported (1,2).
