Latent Class Analysis of Antisocial Behavior: Interaction of Serotonin Transporter Genotype and Maltreatment
To improve understanding about genetic and environmental influences on antisocial behavior (ASB), we tested the association of the 44-base pair polymorphism of the serotonin transporter gene (5-HTTLPR) and maltreatment using latent class analysis in 2,488 boys and girls from Wave 1 of the National Longitudinal Study of Adolescent Health. In boys, ASB was defined by three classes (Exclusive Cove...
متن کاملAssociation of the dopamine transporter (SLC6A3/DAT1) gene 9-6 haplotype with adult ADHD.
ADHD is a neuropsychiatric disorder characterized by chronic hyperactivity, inattention and impulsivity, which affects about 5% of school-age children. ADHD persists into adulthood in at least 15% of cases. It is highly heritable and familial influences seem strongest for ADHD persisting into adulthood. However, most of the genetic research in ADHD has been carried out in children with the diso...
متن کاملThe role of the dopamine transporter DAT1 genotype on the neural correlates of cognitive flexibility.
Cognitive flexibility, the ability to adapt goal-oriented behaviour in response to changing environmental demands, varies widely amongst individuals, yet its underlying neural mechanisms are not fully understood. Neuropharmacological and human clinical studies have suggested a critical role for striatal dopaminergic function mediated by the dopamine transporter (DAT). The present study aimed at...
متن کاملGenetic interaction analysis for DRD4 and DAT1 genes in a group of Mexican ADHD patients.
Attention-deficit hyperactivity disorder (ADHD) is a clinically complex and multifactorial psychiatric disorder of inattention, hyperactivity and impulsivity. Family, twin and adoption studies suggest a genetic influence in the etiology of ADHD. Two variable number of tandem repeats (VNTR) polymorphic systems have been frequently associated with this disorder: the 7 repeat (R) allele in exon 3 ...
متن کاملDopamine Transporter Efflux in ADHD
Elevated dopamine efflux through the dopamine transporter may underlie some forms of attention-deficit hyperactivity disorder (ADHD), according to MazeiRobison et al. The authors identified a mutant form of dopamine transporter in two siblings with ADHD and expressed the mutant and wild-type forms in HEK-293T cells. Although expression levels and dopamine uptake were similar for mutant and wild...
