Human behavioral phenotypes are the result of complex interactions between genotype and the environment. Still, much remains unknown about the gene X environmental basis to adolescent delinquent involvement. Using data from the National Longitudinal Study of Adolescent Health, we examine whether a polymorphism in the dopamine D2 receptor (DRD2) gene interacts with religiosity to predict variati...
Dopamine Genes (DRD2/ANKK1-TaqA1 and DRD4-7R) and Executive Function: Their Interaction with Obesity
Obesity is a multifactorial disease caused by the interaction between genotype and environment, and it is considered to be a type of addictive alteration. The A1 allele of the DRD2/ANKK1-TaqIA gene has been associated with addictive disorders, with obesity and with the performance in executive functions. The 7 repeat allele of the DRD4 gene has likewise been associated with the performance in e...
BACKGROUND Prefrontal behavior and activity in humans are heritable. Studies in animals demonstrate an interaction between dopamine D2 receptors and nicotinic acetylcholine receptors on prefrontal behavior but evidence in humans is weak. Therefore, we hypothesize that genetic variation regulating dopamine D2 and nicotinic acetylcholine receptor signaling impact prefrontal cortex activity and re...
Studies of gene-environment interplay typically focus on one environmental factor at a time, resulting in a constrained view of social context. The concept of environmental contingency is introduced as a corrective. Drawing on the National Longitudinal Study of Adolescent Health and qualitative comparative analysis, the authors focus on an example involving social capital, a gene associated wit...
AIMS Modulation of dopamine receptor D2 (DRD2) activity affects insulin secretion in both rodents and isolated pancreatic β-cells. We hypothesized that single nucleotide polymorphisms in the DRD2/ANKK1 locus may affect susceptibility to type 2 diabetes in humans. METHODS Four potentially functional variants in the coding region of the DRD2/ANKK1 locus (rs1079597, rs6275, rs6277, rs1800497) we...
Dopamine is a major neurotransmitter in the human brain and is associated with various diseases. Schizophrenia, for example, is treated by blocking the dopamine receptors type 2. Shaner, Miller & Mintz (2004) stated that schizophrenia was the low fitness variant of a highly variable mental trait. We therefore explore whether the dopamine receptor 2 gene (DRD2) underwent any selection processes....
INTRODUCTION Ankyrin repeat and kinase domain containing I (ANKK1) and dopamine D2 receptor (DRD2) genes have been associated with psychopathic traits in clinical samples. On the other hand, individuals high in psychopathy show reduced affective priming and deficits in facial expression recognition. We have hypothesized that these emotion-related cognitive phenomena are associated with Taq IA (...
Objective The current study aimed to explore the association of single nucleotide polymorphisms (SNPs) within catechol-O-methyltransferase (COMT) and dopamine receptors with schizophrenia and genetic association with risperidone treatment response. Methods A total of 690 schizophrenic patients (case group) were selected and 430 healthy people were included as the controls. All patients receiv...
Chronic neuroinflammation is a common feature of aging brain and some neurodegenerative diseases, including Parkinson’s disease. However, the molecular mechanisms underlying regulation of innate immunity in the central nervous system remain elusive. Here we show that dopamine receptor D2 (Drd2), known as a critical component for dopamine neurotransmission and a susceptibility gene for Parkinson...
