▶Variants in ABCB1 , TGFB1 , and XRCC1 genes and susceptibility to viral hepatitis A infection in Mexican AmericansAssociationN=6,779Lyna Zhang et al.(2012)· Hepatology
Candidate gene association study of 67 genetic variants in 27 inflammation and DNA repair genes with hepatitis A virus (HAV) infection susceptibility in 6,779 NHANES III participants (2,619 non-Hispanic whites, 2,095 non-Hispanic blacks, 2,065 Mexican Americans). Among Mexican Americans, ABCB1 rs1045642 T allele was associated with lower HAV seropositivity risk (OR=0.79, p<0.001), while TGFB1 rs1800469 and XRCC1 rs1799782 T alleles were associated with increased risk (OR=1.38 and 1.57, respectively). CAT rs769214 and CYP2E1 rs2031920 showed marginal associations with decreased and increased HAV risk, respectively.
▶Influence of neurexin 1 (NRXN1) polymorphisms in clozapine responseReviewRenan P. Souza et al.(2010)· Human Psychopharmacology: Clinical and Experimental
This systematic review of 98 studies examined biological predictors of clozapine response in treatment-resistant schizophrenia patients. Of 379 different gene variants investigated across 70 genetic studies, only three variants (DRD3 Ser9Gly rs6280, HTR2A His452Tyr, and GNB3 C825T) achieved independent replication. Non-genetic predictors included higher prefrontal cortical volumes and lower HVA:5-HIAA ratio in cerebrospinal fluid.
▶Lack of association of GPX1 and MnSOD genes with symptom severity and response to clozapine treatment in schizophrenia subjectsReviewRenan P. Souza et al.(2009)· Human Psychopharmacology: Clinical and Experimental
A systematic review of 98 studies investigating biological predictors of clozapine response in treatment-resistant schizophrenia. Of 70 genetic studies examining 379 variants, only three genetic variants have independently replicated findings: DRD3 Ser9Gly (rs6280), HTR2A His452Tyr, and GNB3 C825T (rs5442/rs5443). Non-genetic predictors include higher prefrontal cortical structural integrity and activity, and lower HVA:5-HIAA ratio in cerebrospinal fluid.
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]
