The 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 کاملEffect of CYP2C9 and VKORC1 genetic variations on warfarin dose requirements in Indian patients.
BACKGROUND Warfarin, an oral anticoagulant is used in patients who are at increased risk of developing blood clots. The management of warfarin therapy is challenging because it shows large inter and intra individual variability in patient response due to factors like age, gender, diet, concurrent drug interactions and variations in CYP2C9 and VKORC1 genes. Studies implicate that polymorphisms i...
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 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 کاملVKORC1 and CYP2C9 genotypic data-based dose prediction alone does not accurately predict warfarin dose requirements in some Malaysian patients.
BACKGROUND/AIM VKORC1 and CYP2C9 genetic polymorphisms may not accurately predict warfarin dose requirements. We evaluated an existing warfarin dosing algorithm developed for Malaysian patients that was based only on VKORC1 and CYP2C9 genes. MATERIALS AND METHODS Five Malay patients receiving warfarin maintenance therapy were investigated for their CYP2C9*2, CYP2C9*3, and VKORC1-1639G>A genot...
