Case-control study of 1,000 Han Chinese individuals (450 epilepsy cases, 550 controls) examining associations between STX1B polymorphisms and epilepsy treatment response. The rs140820592 variant showed significant association with reduced epilepsy risk (OR=0.542, p=0.004) and drug-resistant epilepsy risk (OR=0.260, p=0.004), with eQTL analysis confirming rs140820592 regulates STX1B expression in brain tissues.
About CYP2C19
This gene encodes a member of the cytochrome P450 superfamily of enzymes. The cytochrome P450 proteins are monooxygenases which catalyze many reactions involved in drug metabolism and synthesis of cholesterol, steroids and other lipids. This protein localizes to the endoplasmic reticulum and is known to metabolize many xenobiotics, including the anticonvulsive drug mephenytoin, omeprazole, diazepam and some barbiturates. Polymorphism within this gene is associated with variable ability to metabolize mephenytoin, known as the poor metabolizer and extensive metabolizer phenotypes. The gene is located within a cluster of cytochrome P450 genes on chromosome 10q24. [provided by RefSeq, Jul 2008]
