Attention-deficit hyperactivity disorder (ADHD), substance use disorders, and criminality: a difficult problem with complex solutions.

2014

Abstract The association between attention-deficit hyperactivity disorder (ADHD) and criminality has been increasingly recognized as an important societal concern. Studies conducted in different settings have revealed high rates of ADHD among adolescent offenders. The risk for criminal behavior among individuals with ADHD is increased when there is psychiatric comorbidity, particularly conduct disorder and substance use disorder. In the present report, it is aimed to systematically review the literature on the epidemiological, neurobiological, and other risk factors contributing to this association, as well as the key aspects of the assessment, diagnosis, and treatment of ADHD among offende…

Associations between the dopamine D4 receptor gene polymorphisms and personality traits in elite athletes.

2019

Personality traits and temperament may affect sports performance. Previous studies suggest that dopamine may play an important role in behavior regulation and physical exercise performance. The aim of this study is to determine associations between dopamine D4 receptor gene (DRD4 Ex3) polymorphisms and personality traits (such as neuroticism, extraversion, openness, agreeability and conscientiousness) in elite combat athletes. A total of 302 physically active, unrelated, self-reported Caucasian participants were recruited for this study. The participants consisted of 200 elite male combat athletes and 102 healthy male participants (control group). For personality trait measurements, the NEO…

Dopamine D4 receptor exon III polymorphism, adverse life events and personality traits in a nonclinical German adult sample.

2010

Personality and temperament embrace a wide area of both psychological and behavioral processes which are also based on disposition. A functional polymorphism in exon III of the dopamine D4 receptor gene (DRD4) has been a highly suspect genetic marker for personality in spite of ambiguous results. The present study aimed to further elucidate the relationship between DRD4, negative life events and personality in a representative nonclinical sample. Hundred sixty-seven Germans completed the NEO Five-Factor Inventory, the Tridimensional Personality Questionnaire and the California Adult Q-Sort. A factor analysis revealed 3 factors: emotional stability, social orientation and impulsivity. DNA fr…

Adult attachment and gene polymorphisms of the dopamine D4 receptor and serotonin transporter (5-HTT).

2010

Recently, the Dopamine D4 Receptor Gene (DRD4) and the Serotonin Transporter Gene (5-HTT) have been found to be candidate genes for infant attachment disorganization. The present study aimed to explore the relationship of these genes to adult attachment representations. The Adult Attachment Interview was used to assess attachment representations in 167 German adults. DNA from buccal cells was genotyped for the DRD4 VNTR Exon III and 5-HTT LPR polymorphisms with respect to the presence of the 7repeat allele and the short allele, respectively. DRD4 7repeat allele carriers were significantly more likely to be securely attached than those without 7repeat but only for subjects with unloving care…

2009

Contains fulltext : 80906.pdf (Publisher’s version ) (Closed access) BACKGROUND: Mothers' positive emotions expressed about their children with attention deficit/hyperactivity disorder (ADHD) are associated with a reduced likelihood of comorbid conduct problems (CP). We examined whether this association with CP, and one with emotional problems (EMO), is moderated by variants within three genes, previously reported to be associated with ADHD and to moderate the impact of environmental risks on conduct and/or emotional problems; the dopamine transporter gene (SLC6A3/DAT1), the dopamine D4 receptor gene (DRD4) and the serotonin transporter gene (SLC6A4/5HTT). METHODS: Seven hundred and twenty-…

Partial replication of a DRD4 association in ADHD individuals using a statistically derived quantitative trait for ADHD in a family-based association…

2007

Contains fulltext : 52515.pdf (Publisher’s version ) (Closed access) BACKGROUND: Previous research found an association between single nucleotide polymorphisms (SNPs) in the promoter region of DRD4 and statistically derived phenotypes generated from attention-deficit/hyperactivity disorder (ADHD) symptoms. We sought to replicate this finding by using the same methodology in an independent sample of ADHD individuals. METHODS: Four SNPs were genotyped in and around DRD4 in 2631 individuals in 642 families. We developed a quantitative phenotype at each SNP by weighting nine inattentive and nine hyperactive-impulsive symptoms. The weights were selected to maximize the heritability at each SNP. …

The analysis of 51 genes in DSM-IV combined type attention deficit hyperactivity disorder: association signals in DRD4, DAT1 and 16 other genes.

2006

Contains fulltext : 35205.pdf (Publisher’s version ) (Closed access) Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, starting in early childhood and persisting into adulthood in the majority of cases. Family and twin studies have demonstrated the importance of genetic factors and candidate gene association studies have identified several loci that exert small but significant effects on ADHD. To provide further clarification of reported associations and identify novel associated genes, we examined 1,038 single-nucleotide polymorphisms (SNPs) spanning 51 candidate genes involved in the regulation of neurotransmitter pathways, particularly dopamine, nor…

Identification of two novel polymorphisms and a rare deletion variant in the human dopamine D4 receptor gene

1995

We report two novel polymorphisms and a rare deletion variant in the human dopaine D4 receptor gene. The two polymorphisms are characterized by single base pair substitutions, namely a G-->C transversion changing codon 11 from GGG (encoding Gly) to CGG (encoding Arg) and a C-->T transition in position -11 upstream from the start codon. The Arg11 variant occurs at a frequency of about 1% and the C-->T transition at a frequency of about 7% in German control subjects (n = 148). Allele frequencies observed in patients suffering from schizophrenia (n = 256) and bipolar affective disorder (n = 99) were similar. The deletion variant is characterized by a 21 bp deletion affecting codons 36 to 42 co…

Association between neonatal temperament,SLC6A4,DRD4and a functional polymorphism located inTFAP2B

2011

Genetic studies on human personality have provided little satisfactory results to date mainly because of the complexity of this trait. Neonatal temperament using observational measures is an alternative phenotype to approach genetics to human behavior. An association study was conducted on 117 Caucasian newborns. Their temperament was evaluated using the Neonatal Behavior Assessment Scale 48 h after birth. Thirteen polymorphisms in the SLC6A4, DRD4 and TFAP2B genes were genotyped. Linear regression was performed to analyze data, and Bonferroni correction was applied. To check the functional effect of the TFAP2B Indel Intron 2 polymorphism, reporter gene luciferase assays using a mouse corti…
