▶A common haplotype of DRD3 affected by recent positive selection is associated with protection from schizophreniaMeta-analysisN=1,872Javier Costas et al.(2009)· Human Genetics
This meta-analysis of 794 schizophrenia cases and 1,078 controls from three European populations identified a common protective DRD3 haplotype against schizophrenia (Mantel-Haenszel χ² p-value = 0.00227; OR = 0.79, 95% CI 0.68-0.92). The protective haplotype has reached high frequency in non-African populations through positive selection acting on the non-synonymous SNP rs6280 (Ser9Gly), suggesting natural selection influences susceptibility allele frequencies in psychiatric disorders.
▶SNPs in dopamine D2 receptor gene (DRD2) and norepinephrine transporter gene (NET) are associated with continuous performance task (CPT) phenotypes in ADHD children and their familiesAssociationN=364Kollins SH et al.(2008)· American Journal of Medical Genetics Part B: Neuropsychiatric Genetics
Haplotype-tagging SNP analysis in 364 individuals from 152 ADHD families identified significant associations between commission errors and SNPs in the DRD2 gene (rs2075654, rs1079596) and between reaction time variability and a SNP in the NET gene (rs3785155). These findings suggest that commission errors and reaction time variability are valid ADHD endophenotypes linked to dopaminergic and noradrenergic pathways.
About DRD3
This gene encodes the D3 subtype of the five (D1-D5) dopamine receptors. The activity of the D3 subtype receptor is mediated by G proteins which inhibit adenylyl cyclase. This receptor is localized to the limbic areas of the brain, which are associated with cognitive, emotional, and endocrine functions. Genetic variation in this gene may be associated with susceptibility to hereditary essential tremor 1. Alternative splicing of this gene results in transcript variants encoding different isoforms, although some variants may be subject to nonsense-mediated decay (NMD). [provided by RefSeq, Jul 2008]
