Without correction for multiple testing, we found a significantly increased allele frequency of a common DRD3 gene variant expressing a serine at position 9 in the extracellular N-terminal part of the receptor protein in 55 alcohol-dependent individuals with delirium (chi 2 = 4.1, df = 1, p = 0.042).

While BDNF markers showed no association, a haplotype containing rs3732782, rs905568, and rs7620754 in the 5' region of DRD3 was associated with TD diagnosis (p[10,000 permutations]=0.007).

Whereas the present Swedish case-control analysis did not yield any evidence for association with the diagnosis, the present meta-analysis suggests that the DRD3 gene confer susceptibility to schizophrenia.

We tested for an allelic association between schizophrenia and the DRD3 Mscl alleles, hypothesising heterogeneity between childhood/early adolescence-onset schizophrenia (CO-SZ) and adult-onset schizophrenia (A-SZ).
We suggest that the DRD3Ser9Gly polymorphism may be a contributing factor to the performance of eye movements used as a phenotypic marker of schizophrenia.
We studied the association between polymorphisms of genes coding for dopamine D(2) (DRD2), dopamine D(3) (DRD3), serotonin 2(a) (HTR2A), and serotonin 2(c) (HTR2C) receptors and Antipsychotic-Induced Parkinsonism (AIP), rigidity, bradykinesia, and rest-tremor in African-Caribbeans treated with antipsychotics.
We sought to investigate the relationships between catecholamine-related polymorphisms [dopamine-D(3) receptor (DRD3) Ser9Gly and catechol-O-methyltransferase (COMT) Val158Met] and thermal pain measures in healthy subjects and FM patients.

We provide initial evidence that the BDNF Val66Met and DRD3Ser9Gly genotypes interact only in bipolar-II disorder and that bipolar-I and bipolar-II may be genetically distinct.
We propose that homozygosity for the Bal I polymorphism DRD3 gene is associated with predisposition to substance abuse and/or the pharmacosensitive characteristic of schizophrenia rather than with schizophrenia itself, an hypothesis in agreement with the positive association of this polymorphism with opiate dependence (see companion article by Duaux et al) and the involvement of DRD3 in both pharmacodependence mechanisms and antipsychotic effects of neuroleptics.

We previously reported that YQA31 is a dopamine D3 receptor antagonist with modest 5-HT1A receptor affinity and that it exhibits antipsychotic properties in animal models of schizophrenia.
We present a schizophrenia association study using an extensive linkage disequilibrium (LD) mapping approach in seven candidate genes with a well established link to dopamine, including receptors (DRD2, DRD3) and genes involved in its metabolism and transport (ACE, COMT, DAT, MAO-A, MAO-B).
We performed genotyping for catechol-O-methyltransferase (COMT) Val158Met (rs4680) and dopamine D3 receptor (DRD3) rs6280" genes_norm="1814">Ser9Gly (rs6280) polymorphisms, which were analyzed for associations with pain phenotypes.
We performed an association study between four candidate genes, DRD2, DRD3, DRD4 and 5-HT2A for the presence of tardive dyskinesia (TD) on 84 patients with residual schizophrenia.

We now report evidence for linkage to the ETM locus in three additional, unrelated American families with ET and exclude the FET1 locus in these families.
We made the hypothesis that phenotypical heterogeneity of alcohol-dependence (i.e. the DRD3 gene is a vulnerability gene in a specific subgroup of patients only) could explain these spurious findings, focusing on a core dimension of addictive disorders, namely impulsiveness.
