Research has shown that there are significant ethnic variations in the frequency of highly functional mutations in genes coding for metabolic enzymes. However, few studies have examined the frequency distribution of major allelic variations within the population of Iran. The present study focused on the genotype profile of southern Iranians in order to compare the allelic frequencies of CYP2C9,...
Warfarin is a vitamin K antagonist that genetic and non-genetic factors affected on its doserequirement in the patients with cardio vascular disease. The aim of this study was whetherthe APOE and VKORC1 polymorphisms influence on warfarin dose requirements in the partof Iranian patients. Blood samples were collected from 86 warfarin-treated patients. Afterextraction of genomic DNA, the VKORC1 (...
BACKGROUND Blood anticoagulation after heart valve replacement is a recognized difficulty all over the world. In this study, we identified the effect of amiodarone on the function of warfarin and confirmed the countermeasure by concluding the genotype distribution of vitamin K epoxide reductase complex 1 (VKORC1) and cytochrome P450 2C9 (CYP2C9) of the patient to predict the security dose of wa...
Evaluation of CYP2C9- and VKORC1-based pharmacogenetic algorithm for warfarin dose in Gaza-Palestine
Aim To evaluate applicability of CYP2C9*2, *3 and VKORC1-1639G > A based algorithm to predict warfarin stable dose (WSD) in a group of Palestinian patients. Patients & methods Warfarin doses were retrospectively calculated for 101 Palestinian patients under warfarin therapy using three models. Performance of the three models was assessed in 47 patients found to take WSD. Results Frequency o...
Warfarin is a widely used anticoagulant with a narrow therapeutic index and large interpatient variability in the dose required to achieve target anticoagulation. Common genetic variants in the cytochrome P450-2C9 (CYP2C9) and vitamin K-epoxide reductase complex (VKORC1) enzymes, in addition to known nongenetic factors, account for ~50% of warfarin dose variability. The purpose of this article ...
OBJECTIVES Warfarin oral anticoagulant therapy (OAT) requires regular and frequent drug adjustment monitored by INR. Interindividual variability, drug and diet interferences, and genetics (VKORC1 and CYP2C9) make the maintenance/reaching of stable INR a not so easy task. HPLC assessment of warfarin/enantiomers was suggested as a valid monitoring-tool along with INR, but definite results are sti...
