Abstract
BACKGROUND The most popular tool used for measuring personality traits is the Five-Factor Model (FFM). It includes neuroticism, extraversion, openness, agreeableness and conscientiousness. Many studies indicated the association of genes encoding neurotransmitter receptors/transporters with personality traits. The relationship connecting polymorphic DNA sequences and FFM features has been described in the case of genes encoding receptors of cannabinoid and dopaminergic systems. Moreover, dopaminergic system receives inputs from other neurotransmitters, like GABAergic or serotoninergic systems. METHODS We searched PubMed Central (PMC), Science Direct, Scopus, Cochrane Library, Web of Science and EBSCO databases from their inception to November 19, 2020, to identify original studies, as well as peer-reviewed studies examining the FFM and its association with gene polymorphisms affecting the neurotransmitter functions in central nervous system. RESULTS Serotonin neurons modulate dopamine function. In gene encoding serotonin transporter protein, SLC6A4, was found polymorphism, which was correlated with openness to experience (in Sweden population), and high scores of neuroticism and low levels of agreeableness (in Caucasian population). The genome-wide association studies (GWASs) found an association of 5q34-q35, 3p24, 3q13 regions with higher scores of neuroticism, extraversion and agreeableness. However, the results for chromosome 3 regions are inconsistent, which was shown in our review paper. CONCLUSIONS GWASs on polymorphisms are being continued in order to determine and further understand the relationship between the changes in DNA and personality traits.

Abstract
OBJECTIVE Ser9Gly (rs6280) is a functional single-nucleotide polymorphism (SNP) in the dopamine receptor D3 (DRD3) gene that may be associated with schizophrenia. We performed a meta-analysis to determine whether Ser9Gly influences the risk of schizophrenia and examined the relationship between the Ser9Gly SNP and the etiology of schizophrenia. METHODS Case-control studies were retrieved from literature databases in accordance with established inclusion criteria. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to evaluate the strength of the association between Ser9Gly and schizophrenia. Subgroup analysis and sensitivity analysis were also performed. RESULTS Seventy-three studies comprising 10,634 patients with schizophrenia (cases) and 11,258 controls were included in this meta-analysis. Summary results indicated no association between Ser9Gly and risk of schizophrenia. In the dominant genetic model, the pooled OR using a random effects model was 0.950 (95% CI, 0.847-1.064; P=0.374). CONCLUSION Results of this meta-analysis suggest that the Ser9Gly SNP is not associated with schizophrenia. These data provide possible avenues for future case-control studies related to schizophrenia.

Abstract
We examined 89 normal volunteers using Cloninger's Temperament and Character Inventory (TCI). Genotyping the 102T/C polymorphism of the serotonin 5HT2A receptor gene and the ser9gly polymorphism in exon 1 of the dopamine D3 receptor (DRD3) gene was performed using PCR-RFLP, whereas the dopamine transporter (DAT1) gene variable number of tandem repeats (VNTR) polymorphism was investigated using PCR amplification followed by electrophoresis in an 8% acrylamide gel with a set of size markers. We found a nominally significant association between gender and harm avoidance (P=0.017; women showing higher scores). There was no association of either DAT1, DRD3 or 5HT2A alleles or genotypes with any dimension of the TCI applying Kruskal-Wallis rank-sum tests. Comparing homozygote and heterozygote DAT1 genotypes, we found higher novelty seeking scores in homozygotes (P=0.054). We further found a nominally significant interaction between DAT1 and 5HT2A homo-/heterozygous gene variants (P=0.0071; DAT1 and 5HT2A genotypes P value of 0.05), performing multivariate analysis of variance (MANOVA). Examining the temperamental TCI subscales, this interaction was associated with persistence (genotypes: P=0.004; homo-/heterozygous gene variants: P=0.0004). We conclude that an interaction between DAT1 and 5HT2A genes might influence the temperamental personality trait persistence.

Abstract
Dopamine D3 receptor (DRD3) binds antipsychotic drugs and is abundant in the limbic system of the brain. It has been shown to play important roles in schizophrenia. A number of studies investigated the Ser9Gly polymorphism of the DRD3 gene to test its possible association with schizophrenia; however, the results were inconsistent. Our study aims to further evaluate the possible association between the Ser9Gly polymorphism and schizophrenia using a case-control association study within the Han Chinese population as well as a meta-analysis covering all previous studies. Our study, based on 329 schizophrenic patients and 288 controls, found no significant difference in the genotype or allele distributions of Ser9Gly polymorphism, the meta-analysis showed that the Ser9Gly polymorphism was not associated with Schizophrenia. Our study does not support the contention that the Ser9Gly polymorphism of the DRD3 gene plays a major role in schizophrenia in the Chinese population.

Abstract
BACKGROUND The Ser9Gly polymorphism in dopamine D3 receptor gene (DRD3) was considered an important factor in the pathogenesis of schizophrenia. Allele and genotype frequencies of this polymorphism were studied in different ethnic groups of schizophrenic patients. However, the results have been inconclusive. OBJECTIVE To determine whether the DRD3 Ser9Gly polymorphism is associated with schizophrenia or influences its psychopathological symptoms in Han Chinese population. METHOD We recruited 256 schizophrenic patients and 285 normal controls matched for gender, age and ethnicity. Pretreatment psychotic symptoms were evaluated with the Positive and Negative Symptom Scale (PANSS) in 128 acutely exacerbated schizophrenic in-patients. Genotyping of Ser9Gly polymorphism was performed with a polymerase chain reaction restriction fragment length polymorphism method and reconfirmed by a direct sequencing technique. RESULTS No significant difference was found between either patients with schizophrenia or with more homogeneous schizophrenic subgroups and healthy controls in genotype distributions and allele frequencies for the DRD3 Ser9Gly polymorphism. Similarly, DRD3 Ser9Gly genotype differences failed to reach significance in PANSS global, positive, negative and general symptoms scores. There is a trend (P = 0.064) towards higher PANSS positive symptoms scores in subjects carrying the Gly/Gly genotype. CONCLUSION This study does not support the role of DRD3 Ser9Gly polymorphism in increasing genetic risk for schizophrenia in Han Chinese population. Still, there is a possibility that the DRD3 Ser9Gly variant may reflect genetic variation of severity of positive symptoms in acutely exacerbated schizophrenia. Further studies are warranted to investigate the effect of the DRD3 Ser9Gly polymorphism in relation to longer time course of schizophrenia, including treatment response to antipsychotics.

Abstract
Polymorphisms in the brain-derived neurotrophic factor (BDNF) gene have been suggested to be associated with schizophrenia. In a replication attempt, Swedish patients with schizophrenia (n=187) and control subjects (n=275) were assessed for four BDNF gene polymorphisms. There were no significantly different allele, genotype or haplotype frequencies between cases or controls. Neither were there any differences when schizophrenic patients were sub-divided with regard to a number of different clinical variables, although a small group of psychotic patients with prominent affective features displayed higher frequencies of the less common alleles of the Val66Met and 11757 G/C polymorphisms compared to controls. The present Swedish results do not verify previous associations between putative functional BDNF gene polymorphisms and schizophrenia. However, when combined with previous studies meta-analyses indicated that the BDNF 270 T-allele and the Val66Met homozygous state were associated with the disorder. Thus, the BDNF gene may confer susceptibility to schizophrenia. Additional studies are warranted to shed further light on this possibility.

Abstract
Molecular components of the dopaminergic system may play an important role in the pathophysiology of schizophrenia. In this study, we investigated the relationship of the Ser9Gly (S/G) polymorphism of the dopamine D3 receptor (DRD3) and the variable number of tandem repeats (VNTR) polymorphism of the dopamine transporter (DAT) with therapeutic response to atypical antipsychotics (clozapine, olanzapine, quetiapine, risperidone) and cognitive functions. No associations were found between the DRD3 and DAT polymorphisms and schizophrenia. The S/S genotype and the S allele were more frequent in the non-responder patients (n = 28) than in the group of responders (n = 47) (cut-off: >20-point improvement in Global Assessment of Functioning (GAF) scale). The patients with S/S genotype completed fewer categories and had more perseverative errors in the Wisconsin Card Sorting Test (WCST) compared with the S/G patients. The S/S and S/G patients did not differ in positive and negative symptoms, GAF scores, WCST failure to maintain set, and verbal learning. No differences in symptoms or WCST measures were observed in the patients with different DAT genotypes. These results suggest that the S/S genotype of the DRD3 is associated with worse therapeutic response and more severe executive dysfunctions in patients with schizophrenia.

Abstract
OBJECTIVES Several studies reported contradictory findings regarding the association of major psychosis with CAG repeats in the KCNN3 gene. We investigated the contribution of the CAG repeat at the KCNN3 gene, localized to chromosome 1q21.3, to the genetic susceptibility for schizophrenia, schizoaffective and bipolar disorders. METHODS Analysis of the number of CAG repeats and the differences in allele length were performed for Israeli Ashkenazi Jews, non-Ashkenazi Jews, and Arabs diagnosed with major psychosis (n=181) versus matched ethnic controls (n=207). RESULTS We found no significant difference in the number of CAG repeats between the entire sample of patients and controls. However, an analysis of the differences of allele length revealed a significantly greater number of patients with identical allele length (43.1%) when compared with normal controls (30.4%). Furthermore, an earlier age of non-paranoid schizophrenia onset was found associated with differences in allele sizes. There were no significant differences in the number of CAG repeats and the differences in allele length when subjects were grouped according to gender, ethnic origins of their parents, family history, and diagnostic groups. CONCLUSIONS Our results support the hypothesis that a contribution of the KCNN3 gene to genetic susceptibility to major psychosis and their phenotypic polymorphism may be related to the difference of allele length rather than to the number of CAG repeats.

Abstract
OBJECTIVE To further evaluate the controversial putative association between a Ser9Gly variant in the first exon of the dopamine D3 receptor gene (DRD3) and schizophrenia. METHODS Swedish patients with schizophrenia ( n=156) and control subjects ( n=463) were assessed for the DRD3 Ser9Gly variant. Meta-analyses including previous and the present Swedish case-control results were performed. RESULTS No significant difference between the Swedish patients and controls were found, but there was an association between DRD3 Ser9Gly Ser/Ser and homozygous genotypes and response to anti-psychotic drugs. This finding was supported by an incomplete meta-analysis. In a meta-analysis of all case-control studies comprising 8761 subjects the association between DRD3 Ser9Gly homozygosity and schizophrenia ( =4.96, degree of freedom=1, p <0.05, odds ratio=1.10, 95% confidence interval=1.01-1.20) persisted. However, the previously proposed association between the Ser/Ser genotype and schizophrenia was not significant (chi2 =2.71, degree of freedom=1, p>0.05, odds ratio=1.08, 95% confidence interval=0.99-1.17). CONCLUSIONS 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. Reasons for the discrepancies between prior studies are discussed.

Abstract
Altered dopamine neurotransmission and eye movement disturbances have been implicated in the pathogenic process of schizophrenia. So far, molecular genetic studies have shown little association between schizophrenia and polymorphism of any dopamine receptor or transporter genes except for some findings concerning D3 receptor (DRD3) gene. Eye movement disturbances occur in a majority of patients with schizophrenia and in a proportion of their first-degree relatives and they have been suggested as a phenotypic marker in genetic studies of this illness. Here we report an association between the Ser9Gly polymorphism of the DRD3 gene and the intensity of eye movement disturbances (fixation and smooth pursuit) observed in 119 schizophrenic patients and in 94 unrelated healthy control subjects. In schizophrenic patients, the mean intensity of both kinds of eye movement disturbances was highest in individuals with the Ser-Ser genotype, significantly lower in Ser-Gly and lowest in the Gly-Gly genotype. The Ser-Ser genotype was more prevalent in patients with a higher intensity of both fixation (58.1 vs 23.9% P < 0.001) and smooth pursuit disturbances (52.3 vs 25.8%, P < 0.02) and the Ser-Gly genotype frequency was lower in patients with higher fixation disturbances (37.0 vs 60.9%, P < 0.02). In control subjects, the genotype frequency Ser-Ser was higher in subjects with any degree of eye movement disturbances compared to subjects without such disturbances both for fixation and smooth pursuit performance (81.0 vs 50.7%, P < 0.05 and 79.2 vs 50.0%, P < 0.05, respectively). In control subjects the frequency of Ser-Gly was lower in the first group, for either fixation or smooth pursuit, compared to normal performers (9.5 vs 43.8%, P < 0.01 and 8.3 vs 45.7, P < 0.005, respectively). We suggest that the DRD3 Ser9Gly polymorphism may be a contributing factor to the performance of eye movements used as a phenotypic marker of schizophrenia.
