We previously reported three naturally occurring genetic polymorphisms (125C>G, Pro42Arg, CYP1A2*15; 1130G>A, Arg377Gln, *16; and 1367G>A, Arg456His, *8) found in a Japanese population. The enzyme's endogenous substrate is unknown; however, it is able to metabolize some PAHs to carcinogenic intermediates. Kinetic analysis for 7-ethoxyresorufin O-deethylation revealed that V(max) and V(max)/K(m) of all three variants were less than 3 and 1% of the WT, respectively, although the K(m) value was significantly increased only in the Arg377Gln variant (approximately a 9-fold increase).

VEN is metabolized mainly by CYP2D6 and to a minor extent by CYP2C19 to the major active metabolite O-desmethylvenlafaxine (ODV). and abstracted bioactivities (e.g. Instantané N° 20 mars 2006 CYP1A2. Japanese patent number 05719026 Chida et al, 1999. 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. This gene encodes a member of the cytochrome P450 superfamily of enzymes. 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).

Variations in the activity of CYP1A2 can result in an increase or decrease of the metabolisation of medicines.
