|
0.070 | GeneticVariation | BEFREE | COMT Val158Met and DRD2 Taq1A may confer their risk of alcohol dependence through reduced dopamine receptor sensitivity in the prefrontal cortex and hindbrain, respectively. | 22474103 | 2012 |

0.070 | GeneticVariation | BEFREE | It is possible that the rs165774 SNP, in combination with rs4680, results in a common molecular variant of COMT that contributes to schizophrenia and alcohol dependence susceptibility. | 22208661 | 2011 |

|
0.070 | GeneticVariation | BEFREE | The paper focuses on such candidate gene polymorphisms that alter alcoholism-related intermediate phenotypes including: dopaminergic system polymorphic variants (DRD2 -141C Ins/Del in promoter region, exon 8 and DRD2 TaqI A and DAT 40bp VNTR genes polymorphisms) that cause predisposition to severe alcoholism (haplotype Ins/G/A2); COMT Val158Met gene polymorphism related to differences in executive cognitive function and 5-HTT gene promoter polymorphism, which alters stress response and affects anxiety and dysphoria. | 17079080 | 2006 |

|
0.070 | GeneticVariation | BEFREE | Our COMT Val158Met results suggest that there may be both sex differences in the genetic origins of alcoholism and smoking in this population and overlap in genetic vulnerability to both addictions in women. | 16499480 | 2006 |

|
0.070 | GeneticVariation | BEFREE | Functional alleles that alter alcoholism-related intermediate phenotypes include common alcohol dehydrogenase 1B and aldehyde dehydrogenase 2 variants that cause the aversive flushing reaction; catechol-O-methyltransferase (COMT) Val158Met leading to differences in three aspects of neurobiology: executive cognitive function, stress/anxiety response, and opioid function; opioid receptor micro1 (OPRM1) Asn40Asp, which may serve as a gatekeeper molecule in the action of naltrexone, a drug used in alcoholism treatment; and HTTLPR, which alters serotonin transporter function and appears to affect stress response and anxiety/dysphoria, which are factors relevant to initial vulnerability, the process of addiction, and relapse. | 15584875 | 2004 |
