ABSTRACTBackground: Currently, no pharmacogenetic tests for selecting an opioid-dependence pharmacotherapy have been approved by the US Food and Drug Administration. 14. CYP1A2*1F. The enzyme's endogenous substrate is unknown; however, it is able to metabolize some PAHs to carcinogenic intermediates. Mutat Res Genet Toxicol Environ Mutagen. In this study, these variant enzymes were expressed in Chinese hamster V79 cells, and their mRNA and protein expression levels as well as catalytic activities were determined. Log concentration/dose ratios for citalopram were significantly different across all CYP2C19 phenotype classifications as defined by the pharmacogenomic test (p=0.0007; Fig. Antibody information for antibodies CAB016531 used in analysis of ENSG00000140505 / CYP1A2 (CP12, P3-450) National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. 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). 2008. *11 c.558C>A *15 c.125C>G *16 c.1130G>A CYP2C19b *2 c.681G>A *3 c.636G>A *4 c.1A>G *5 c.1297C>T *6 c.395G>A *7 c.819+2T>A *8 c.358T>C *9 c.431G>A *10 c.680C>T *17 c.-806C>T CYP2C9b *2 c.430C>T *3 c.1075A>C *4 c.1076T>C *5 c.1080C>G ... b For CYP1A2… 558C>A was characterized by a cDNA-mediated expression system using Chinese hamster V79 cells.

CYP1A2 cytochrome P450 family 1 subfamily A member 2 Gene ID: 1544, updated on 24-Nov-2020 Gene type: protein coding Also known as: CP12; CYPIA2; P3-450; P450(PA) See all available tests in GTR for this gene; Go to complete Gene record for CYP1A2; Go to Variation Viewer for CYP1A2 variants ; Summary. 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. Use of combinatorial pharmacogenomic testing in two cases from community psychiatry Eve S Fields,1 Raymond A Lorenz,2 Joel G Winner2 1Northwest Center for Community Mental Health, Reston, VA, USA; 2Assurex Health, Mason, OH, USA Abstract: This report describes two cases in which pharmacogenomic testing was utilized to guide medication selection for difficult to treat patients.
