Inter-individual variability of in vivo CYP2D6 activity in different genotypes.

Identification of New Alleles and the Determination of Alleles and Genotypes Frequencies at the CYP2D6 Gene in Emiratis

CYP2D6 belongs to the cytochrome P450 superfamily of enzymes and plays an important role in the metabolism of 20-25% of clinically used drugs including antidepressants. It displays inter-individual and inter-ethnic variability in activity ranging from complete absence to excessive activity which causes adverse drug reactions and toxicity or therapy failure even at normal drug doses. This variab...

Inter-individual Variability of Coumarin 7-hydroxylation (CYP2A6 activity) in an Iranian Population

P-192: Association of Cytochrome P450 2D6 (CYP2D6) Gene Polymorphism with Clomiphene Citrate Treatment in Iranian Infertile Women with Polycystic Ovary Syndrome

Background: Clomiphene Citrate (CC) is the most frequently administered drug for the treatment of female infertility [e.g. polycystic ovary syndrome (PCOS)]; which aims at restoring ovulation. Clomiphene is metabolized by CYP2D6, an important enzyme responsible for the metabolism of approximately 25% of clinically used drugs. CYP2D6 is very polymorphic and thought to result in inter- individual...

Variability in antioxidant activity and phenolic profile in different parts of sunflower (Helianthus annuus L.) genotypes

Sunflower (Helianthus annuus L.) is largely consumed in Iran as an oleaginous and confectionery product. In this study, the total phenolic and flavonoid contents, antioxidant activity and phenolic composition in different parts of the seeds from six sunflower genotypes were investigated. The antioxidant activity of extract was evaluated by different assays. The total phenolic and flavonoid cont...

Distribution of CYP2D6 Alleles and Phenotypes in the Brazilian Population

The CYP2D6 enzyme is one of the most important members of the cytochrome P450 superfamily. This enzyme metabolizes approximately 25% of currently prescribed medications. The CYP2D6 gene presents a high allele heterogeneity that determines great inter-individual variation. The aim of this study was to evaluate the variability of CYP2D6 alleles, genotypes and predicted phenotypes in Brazilians. E...
