Polymorphisms of VKORC1 and CYP2C9 are associated with warfarin sensitivity in Chinese population
OBJECTIVE Warfarin is a commonly prescribed anticoagulant for prevention of thromboembolic events. Wide inter-individual dose variation, narrow therapeutic range and risk of serious bleeding result in difficulties in achieving the therapeutic effect. The present study was designed to clarify the real biological significance of the polymorphisms of VKORC1 and cytochrome P450 2C9 (CYP2C9) in warf...
متن کاملEffect of Cyp2c9 and Vkorc1 Genetic Polymorphisms on Warfarin Dose Requirement in South Indian Population
Cytochrome P450 2C9 (CYP2C9) and vitamin K epoxide reductase complex subunit 1 (VKORC1) genetic polymorphisms were strongly associated with warfarin dose requirement in Caucasians, African Americans and other populations. Our aim was to evaluate the effect of CYP2C9 and VKORC1 genetic polymorphisms on warfarin dose requirement in south Indian population. A total of 150 patients on warfarin with...
متن کاملThe effect of CYP2C9 and VKORC1 genetic polymorphisms on warfarin dose requirements in a pediatric population
OBJECTIVE The aim was to investigate the frequency of genetic polymorphisms of cytochrome P4502C9 (CYP2C9) and vitamin K epoxide reductase complex subunit1 (VKORC1) and determine the effect of these polymorphisms on warfarin dose requirements in pediatric patients. METHODS Fifty-eight pediatric patients with cardiac disease, thrombophilia, or other conditions, taking a stable warfarin dose, a...
متن کاملWarfarin dose and INR related to genotypes of CYP2C9 and VKORC1 in patients with myocardial infarction
BACKGROUND Warfarin treatment has a narrow therapeutic range, requiring meticulous monitoring and dosage titration. Individual dosage requirement has recently partly been explained by genetic variation of the warfarin metabolizing enzyme CYP2C9 and the Vitamin K-activating enzyme VKORC1. In the WARIS-II study, comparing three different antithrombotic regimens after myocardial infarction, warfar...
متن کاملThe Contribution of VKORC1 and CYP2C9 Genetic Polymorphisms and Patients’ Demographic Characteristics with Warfarin Maintenance Doses: A Suggested Warfarin Dosing Algorithm
The requirement of varying doses of warfarin for different individuals can be explained by environmental and genetic factors. We evaluated the frequency of vitamin K epoxide reductase complex subunit 1 (VKORC1) and cytochrome P450 2C9 (CYP2C9) variants together with patientdemographic characteristics and investigated their association with warfarin dose requirement with the ob...
