Influence of ANKK1 and DRD2 polymorphisms in response to haloperidol
AssociationN=88Ina Giegling et al.(2013)· European Archives of Psychiatry and Clinical Neuroscience

This study investigated whether 9 ANKK1 and 27 DRD2 SNPs predict haloperidol efficacy and tolerability in 88 acutely psychotic patients. rs2242592 in ANKK1 (p=0.008) and rs1124493 in DRD2 (p=0.001) were significantly associated with improved clinical response on PANSS scores. Three haplotype blocks (one in ANKK1, two in DRD2) were also associated with better clinical improvement. Results showed partial replication in the CATIE schizophrenia sample, with rs11604671 (in LD with rs2242592) associated with response, suggesting ANKK1 and DRD2 variability influences haloperidol response though further validation is needed.

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 families
AssociationN=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 DRD2

This gene encodes the D2 subtype of the dopamine receptor. This G-protein coupled receptor inhibits adenylyl cyclase activity. A missense mutation in this gene causes myoclonus dystonia; other mutations have been associated with schizophrenia. Alternative splicing of this gene results in two transcript variants encoding different isoforms. A third variant has been described, but it has not been determined whether this form is normal or due to aberrant splicing. [provided by RefSeq, Jul 2008]
