Six novel nonsynonymous CYP1A2 gene polymorphisms: catalytic activities of the naturally occurring variant enzymes. CYP1A2 is part of the cytochrome P450 family of drug-metabolizing enzymes and is responsible for the metabolism of approximately 9% of prescription drugs. The 5HTTLPR-relevant regions within SLC6A4 and the 102T>C allele of HTR2A were amplified using PCR. These results suggest that Pro42, Arg377, and Arg456 are critical amino acids for the production of catalytically active CYP1A2 holoenzyme. Decreased . USA.gov. Conversely, smoking is a well-known activator of CYP1A2 (especially the CYP1A2*1F form), resulting in faster … Drug Metab Dispos. In the reduced CO difference spectral analysis using recombinant proteins produced in the Sf21/baculovirus system, the peak at 450 nm seen in the WT protein was hardly observed in the three variants, suggesting marked reductions in their hemoprotein formation. *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 *6 c.818del *8 c.449G>A *9 c.752A>G *11 c.1003C>T CYP2D6b,c *2A c.-1589C>G, c.886C>T *2 c.886C>T *3 c.775del *4 … 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. 2008.

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. Cardiotoxicity has been extensively reported in venlafaxine (VEN) overdoses. The presence of conserved regions in intron 1 suggests that regulatory elements are located in this region. … Lim YR, Kim IH, Han S, Park HG, Ko MJ, Chun YJ, Yun CH, Kim D. Biomol Ther (Seoul).

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).

This gene encodes a member of the cytochrome P450 superfamily of enzymes. Zhong Nan Da Xue Xue Bao Yi Xue Ban. High cytoplasmic expression exclusively in hepatocytes. Documentation - Document non contractuel. Summary of CYP1A2 (CP12, P3-450) expression in human tissue. 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). Human cytochrome P450 1A2 (CYP1A2) catalyzes the metabolism of many important drugs and environmental chemicals. The 5HTTLPR-relevant regions within SLC6A4 and the 102T>C allele of HTR2A were amplified using PCR. The CYP1A2 SNPs were converted into star nomenclature as defined by the Karolinska Institute, which included the *1B,*1F, *1L and *1N alleles. The following CYP1A2 SNPs were identified: −3860G>A, −2467delT, −739T>G, −729C>T, −163C>A, 125C>G, 558C>A, 2116G>A, 2473G>A, 2499A>T, 3497G>A, 3533G>A, 5090C>T, 5166G>A, 5347C>T. CYP1A2.1-739T>G .

[38] An allele is one of the possible forms of a gene, and certain forms have been associated with altered enzyme activity — meaning that your specific form of CYP1A2 could impact how you process and metabolize certain medications. 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.
