This study investigated the impact of genetic and nongenetic factors on warfarin dose requirements in Egyptians . DNA was extracted from 50 patients taking warfarin for more than 1 year and genotyped for VKORC1 (1173 C> T) , CYP2C9 *3 (1075 C>)gene polymorphisms using SYBR Green - based multiplex allele - specific PCR ER -
