The polymorphic nature of the human dopamine D4 receptor gene: A comparative analysis of known variants and a novel 27 bp deletion in the promoter region
TLDR
Remarkably, the deleted region of the DRD4 gene contains consensus sequences of binding sites for several known transcription factors, suggesting that the different alleles may affect the transcriptional regulation of the gene.
Dopamine D4 receptor variant, D4GLYCINE194, in Africans, but not in Caucasians: no association with schizophrenia.
TLDR
None of the 147 Caucasians (113 controls; 34 schizophrenics) revealed this variant, termed D4GLYCINE194, which occurs one amino acid away from a serine amino acid which is critical for the attachment of dopamine.
Systematic screening for mutations in the coding region of the human serotonin transporter (5-HTT) gene using PCR and DGGE.
TLDR
Structural modifications of the 5-HTT gene do not seem to play either a major or minor role in the genetic predisposition to mood disorder or obsessive-compulsive disorder.

TLDR
It is shown by DNA resequencing/haplotyping of 600 DRD4 alleles, representing a worldwide population sample, that the origin of 2R–6R alleles can be explained by simple one-step recombination/mutation events and the 7R allele originated as a rare mutational event that nevertheless increased to high frequency in human populations by positive selection.
The world-wide distribution of allele frequencies at the human dopamine D4 receptor locus
TLDR
A global survey of the DRD4 repeat polymorphism indicates that the polymorphism is ancient and arose before the global dispersion of modern humans and emphasizes the importance of population considerations in the design and interpretation of any association studies carried out with this polymorphism.
A genetic polymorphism in the promoter region of DRD4 associated with expression and schizophrenia.
TLDR
Although the association is weak and should be considered tentative until other studies replicate it, this polymorphism provides a tool with the potential to examine whether DRD4 is related to susceptibility to and neuroleptic response in schizophrenia.
Analysis of clozapine response and polymorphisms of the dopamine D4 receptor gene (DRD4) in schizophrenic patients.
We have examined the hypothesis that a variable number of tandem repeats in the third cytoplasmic loop of the dopamine D4 receptor influences clinical response to clozapine using a sample of 189

Multiple dopamine D4 receptor variants in the human population
TLDR
This is the first report of a receptor in the catecholamine receptor family that displays polymorphic variation in the human population and such variation among humans may underlie individual differences in susceptibility to neuropsychiatric disease and in responsiveness to antipsychotic medication.
Cloning of the gene for a human dopamine D4 receptor with high affinity for the antipsychotic clozapine
TLDR
The cloning of a gene that encodes a dopamine receptor gene that has high homology to the human dopamine D2 and D3 receptor genes is reported, which suggests the existence of other types of dopamine receptors which are more sensitive to clozapine.
Human dopamine D1 receptor encoded by an intronless gene on chromosome 5
TLDR
The cloning of the D1 receptor gene is reported, which resides on an intronless region on the long arm of chromosome 5, near two other members of the G-linked receptor family, and binds drugs with affinities identical to the native human D1 receptors.

TLDR
The isolation and characterization of a rat gene encoding a dopamine receptor that is structurally and functionally similar to the D1 dopamine receptor is described and it is proposed that this dopamine receptor subtype be called D1B.
Cloning and expression of human and rat Dt dopamine receptors
TLDR
The cloning of human and rat D1 dopamine receptors by applying an approach based on the polymerase chain reaction is reported, which reveals that it is a G protein-coupled receptor.
Cloning of the cDNA and gene for a human D2 dopamine receptor.
TLDR
A clone encoding a human D2 dopamine receptor was isolated from a pituitary cDNA library and sequenced, and it was shown that the coding sequence is interrupted by six introns and that the additional amino acids present in the human pituitsary receptor are encoded by a single exon of 87 base pairs.
Molecular cloning and characterization of a novel dopamine receptor (D3) as a target for neuroleptics
TLDR
The D3 receptor is localized to limbic areas of the brain, which are associated with cognitive, emotional and endocrine functions, and seems to mediate some of the effects of antipsychotic drugs and drugs used against Parkinson's disease.
Paranoid psychosis (delusional disorder) and schizophrenia. A family history study.
TLDR
Investigators should take cognizance of the entity of DD as one possible source of the heterogeneity within "schizophrenia," as it is found that inferiority feelings clustered significantly in the relatives of the DD probands.
Psychiatric illness in first-degree relatives of patients with paranoid psychosis, schizophrenia and medical illness.
TLDR
The results of this study support the familial independence of delusional disorder and schizophrenia.

TLDR
Although some of the data is consistent with the view that SDD is a "mild" form of schizophrenia, the bulk of the evidence suggests thatSDD and schizophrenia are distinct syndromes.
