deletion or LOH and are excluded by default. The first chart in this section shows a summary of the types of Markov models. Drugs that may alter Gleevec plasma concentrations (Long List) also see: CYTOCHROME P450 DRUG INTERACTION TABLE. This section shows the drugs associated with CYP2B6 resistance mutations. Keep in mind that many drugs, toxins, and endogenous substances can be metabolized using multiple different CYP enzymes. reload the genome browser. The gene view histogram is a graphical view of mutations across CYP2B6. This means most drugs come to market with incomplete drug interaction profiles. separate page. Genetic or tumor testing maybe needed to establish the indication for use of this drug. The information presented here is NOT A COMPLETE LIST of CYP2B6 inducers, inhibitors, and substrates; Not all drug interactions are clinically significant. Methadone is a long-acting opioid with considerable unexplained interindividual variability in clearance. This section shows publications associated with CYP2B6. CYP2B6 (Cytochrome P450 Family 2 Subfamily B Member 6) is a Protein Coding gene. the same genomic position on both the canonical and alternative transcripts The information presented here is NOT A COMPLETE LIST of CYP2B6 inducers, inhibitors, and substrates. Carbamazepine. mexiletine chlorpromazine nebivolol citalopram perhexiline clomipramine propafenone cocaine propranolol doxepin sparteine escitalopram timolol haloperidol. CYP2B6 is a minor contributor to hepatic nicotine metabolism, but the enzyme has been proposed as relevant to nicotine‐related behaviors because of reported CYP2B6 mRNA expression in human brain tissue. displayed. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. To include these This section shows the drugs associated with You can see more information in our may display a blank content panel when switching between browser Hence, for drugs that are metabolized by CYP2D6 (that is, are CYP2D6 substrates), certain individuals will eliminate these drugs quickly (ultrarapid metabolizers) while others slowly (poor metabolizers). the table may give a value of greater than 100%. button. (Functional Analysis through Hidden Markov Models). In Asians, roughly 12% to 23% are poor metabolizers for CYP2C19. Legacy mutation identifier (COSM) represents existing COSM mutation identifiers. Das Therapeutische Drug-Monitoring-Programm KONBEST (siehe DAZ 2012; Nr. Phenobarbital Phenytoin. 2 of 2 List Updated April 13, 2020 rs3745274 CYP2B6 (and variants), POR (and variants), and cytochrome b 5 (wild-type) were coexpressed in a cell system. Show more. You can find CYP2B6 ultrarapid metabolizer: An individual carrying two increased function alleles *4/*4, *22/*22, *4/*22: CYP2B6 rapid metabolizer same drug(s), and the distribution of mutations that occur in those provides accurate and independent information on more than 24,000 prescription drugs, over-the-counter medicines and natural products. toxicants and carcinogens) and endogenous substances. and deletions. Indiana University School of Medicine (2007). You have hidden all of the sections. Cytochrome P450 (often abbreviated "CYP") is a class of enzymes that is involved in the metabolism of many medications, Cytochrome P450 enzymes are located primarily in the liver, Cytochrome P450 enzymes are subdivided into classes (e.g. Note: CYP3A4 is the main enzyme that metabolizes Gleevec and therefore effects may be more pronounced that those related to CYP2D6 3A only), or they may be metabolized by a number of CYP enzymes (ex. These mutations are displayed at the amino acid level across the informative for defining high level amplification, homozygous K I and k inact were found to be 0.498 μ M and 0.079 min−1, respectively. golimumab, Simponi®, infliximab, Remicade®) [6], Isotretinoin (Accutane®, Claravis®, etc.) and whole genomes/exome resequencing where all the protein coding genes have Where FATHMM-MKL scores are ≥ 0.7 the mutation is classified resistant mutations are not located on the canonical transcript but are on 2. You can use the filters panel to select the types of data that are 2C8, 3A4, and 2C19), In some cases, one CYP enzyme may be responsible for the majority of the drug's metabolism while other CYP enzymes contribute a nonsignificant amount of metabolism, Certain chemicals and foods (ex. close proximity to CYP2B6 please use the Note: in some web browsers the genome browser This material is provided for educational purposes only and is not intended for medical advice, diagnosis or treatment. CYP2D6 Genetic … If a drug is metabolized too quickly, it may decrease the drug's efficacy while if the drug is metabolized too slowly, toxicity may result. Alternative transcripts are also displayed here for genes where reported Genetic and several nongenetic factors affect the activity of CYP2B6. Note that in patients genetically deficient in CYP2D6 who are taking a CYP2D6 substrate, the addition of a CYP2D6 inhibitor will not result in any cha… Beta-Value > 0.8 and differs from normal average by > 0.5, Beta-Value < 0.2 and differs from normal average by > 0.5. CYP2B6 is expressed in the liver and constitutes less than 1% of the total hepatic CYP content. Use the list on the left to show Links to bioinformatics resources that are related to CYP2B6. **This drug is listed on the Additional Pharmacogenomic Genes & Associated Drugs table. This protein localizes to the endoplasmic reticulum and its expression is induced by phenobarbital.
