英文摘要: Abstract(#br) Objective(#br)Cytochrome P450 2C9 and 2C19 ( CYP2C9 and CYP2C19 , respectively) genetic polymorphisms play an important role in phenytoin (PHT) metabolism. We have evaluated whether these genetic polymorphisms have an effect on PHT-induced neurological toxicity in Tamilian (ethnic group native to southern India) patients with epilepsy.(#br) Methods(#br)We studied 292 Tamilian patients who were taking PHT for the treatment of various epileptic seizures. PHT toxicity was defined on the basis of neurological signs of toxicity and further sub-classified into mild, moderate, and severe toxicity based on clinical severity. Genomic DNA was extracted from peripheral leukocytes and genotyped for CYP2C9*2 , *3 and CYP2C19*2 , *3 by PCR-restriction fragment length polymorphism...
