Interrogation of CYP2D6 Structural Variant Alleles Improves the Correlation Between CYP2D6 Genotype and CYP2D6‐Mediated Metabolic Activity

Clinical and Translational Science, 2020
The cytochrome P450 2D6 (CYP2D6) gene locus is challenging to accurately genotype due to numerous single nucleotide variants and complex structural variation.

Hepatic cytochromes P450: structural degrons and barcodes, posttranslational modifications and cellular adapters in the ERAD-endgame. [PDF]

, 2016
The endoplasmic reticulum (ER)-anchored hepatic cytochromes P450 (P450s) are enzymes that metabolize endo- and xenobiotics i.e. drugs, carcinogens, toxins, natural and chemical products.

Uptake of DPYD and UGT1A1 testing in Italy and adherence to pharmacogenetic guidelines: A 5‐year perspective from an EQA provider

British Journal of Clinical Pharmacology, EarlyView.
Aims Pharmacogenetic implementation requires awareness of the state‐of‐the‐art practice of laboratories providing pharmacogenetic testing. This study investigated how pharmacogenetic guidelines and recommendations have been implemented over time by Italian laboratories participating in the external quality assessment (EQA) Pharmaco‐scheme established ...

The Impact of CYP2D6 Genotyping on Tamoxifen Treatment [PDF]

Pharmaceuticals, 2010
Tamoxifen remains a cornerstone of treatment for patients with oestrogen-receptor-positive breast cancer. Tamoxifen efficacy depends on the biotransformation, predominantly via the cytochrome P450 2D6 (CYP2D6) isoform, to the active metabolite endoxifen.

Pharmacogenomics in clinical practice: Biomarker information in Brazilian drug labels

British Journal of Clinical Pharmacology, EarlyView.
This review examines the PGx annotations in package inserts (bulas in Brazilian Portuguese) approved by ANVISA, the Brazilian Health Regulatory Agency, for 19 gene–drug pairs with strong or moderate recommendations for initial dosing alteration in the CPIC (Clinical Pharmacogenetic Implementation Consortion) guidelines and PGx testing required or ...

In vitro comparative analysis of metabolic capabilities and inhibitory profiles of selected CYP2D6 alleles on tramadol metabolism

Clinical and Translational Science
Tramadol, the 41st most prescribed drug in the United States in 2021 is a prodrug activated by CYP2D6, which is highly polymorphic. Previous studies showed enzyme‐inhibitor affinity varied between different CYP2D6 allelic variants with dextromethorphan ...

An increase in urinary primaquine and a reduction in urinary primaquine-5,6-orthoquinone in the Thai population with CYP2D6 reduced enzyme function

Heliyon
Objectives: Primaquine is metabolized by the cytochrome P450-2D6 enzyme (CYP2D6) to an active primaquine-5,6-orthoquinone (POQ). No relationships of CYP2D6 polymorphisms with the pharmacokinetics of primaquine and POQ were reported in the Thai population.

The relationship between plasma concentration of metoprolol and CYP2D6 genotype in patients with ischemic heart disease [PDF]

, 2014
Background Metoprolol is the one of the most commonly used β-blockers in the treatment of ischemic heart disease and it is extensively metabolized in the liver undergoing oxidation by CYP2D6 isoenzyme of cytochrome P450.

Cholic Acid Feeding Leads to Increased CYP2D6 Expression in CYP2D6-Humanized Mice [PDF]

Drug Metabolism and Disposition, 2017
Cytochrome P450 2D6 (CYP2D6) is a major drug-metabolizing enzyme, but the factors governing transcriptional regulation of its expression remain poorly understood. Based on previous reports of small heterodimer partner (SHP) playing an important role as a transcriptional repressor of CYP2D6 expression, here we investigated how a known upstream regulator

Pharmacokinetic profiles of sertraline in pregnancy as a predictor of postpartum depressive symptoms

British Journal of Clinical Pharmacology, EarlyView.
Aim To characterize pharmacokinetic changes of sertraline and its metabolite during pregnancy and postpartum, and their relationship to maternal postpartum depressive symptoms. Methods This was a prospective observational, longitudinal study of pregnant women with a major depressive disorder treated with sertraline (N = 185 women, 205 pregnancies ...
