▶Informed Genome‐Wide Association Analysis With Family History As a Secondary Phenotype Identifies Novel Loci of Lung CancerAssociationN=23,669Julia G. Poirier et al.(2015)· Genetic Epidemiology
A two-stage GWAS with meta-analysis of 11,463 lung cancer cases and 12,206 controls identified 30 validated genetic variants (25 loci) associated with lung cancer susceptibility, with emphasis on variants associated with family history. Top findings include rs12415204 in FFAR4 (chr10q23.33; OR=1.09, 95% CI 1.04-1.14, P=1.63×10⁻⁴) and rs1158970 in KCNIP4 (chr4p15.2; OR=0.89, 95% CI 0.85-0.94, P=9.64×10⁻⁶). Four replicated variants function as eQTLs in lung tissue.
▶New genetic evidence for involvement of the dopamine system in migraine with auraAssociationN=1,300Unda Todt et al.(2009)· Human Genetics
This case-control association study of 650 German migraine with aura (MA) patients and 650 controls tested 53 variants across 10 dopaminergic system genes. Three SNPs in the dopamine-beta hydroxylase (DBH), dopamine transporter (SLC6A3), and dopamine D2 receptor (DRD2) genes showed significant associations with MA. After gene-wide correction, rs2097629 in DBH (OR=0.77, p=0.0012) and rs40184 in SLC6A3 (OR=0.81, p=0.0082) remained significant, with supporting evidence from 2,937 British controls. These findings provide genetic evidence for dopaminergic system involvement in MA pathogenesis.
▶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 DBH
The protein encoded by this gene is an oxidoreductase belonging to the copper type II, ascorbate-dependent monooxygenase family. The encoded protein, expressed in neuroscretory vesicles and chromaffin granules of the adrenal medulla, catalyzes the conversion of dopamine to norepinephrine, which functions as both a hormone and as the main neurotransmitter of the sympathetic nervous system. The enzyme encoded by this gene exists exists in both soluble and membrane-bound forms, depending on the absence or presence, respectively, of a signal peptide. Mutations in this gene cause dopamine beta-hydroxylate deficiency in human patients, characterized by deficits in autonomic and cardiovascular function, including hypotension and ptosis. Polymorphisms in this gene may play a role in a variety of psychiatric disorders. [provided by RefSeq, Aug 2017]
