Estudio de asociación entre genotipo de DAT1 y transtorno por déficit de atención / hiperactividad

, 2013
Introducción: El TDAH tiene un componente genético importante; el gen de transportador de Dopamina (DAT1) se ha asociado con susceptibilidad al TDAH y con sus endofenotipos. El VNTR de 40pb en la región 3’UTR aumenta la expresión del DAT1.

Adaptive Channel‐Robust Signal Fusion Method for Collaborative Device Fingerprint Identification

Electronics Letters, Volume 61, Issue 1, January/December 2025.
In this letter, we presented a high‐performance collaborative radio frequency fingerprint identification (Co‐RFFI) method considering the multi‐source and channel‐varying signals. By the well‐designed adaptive channel‐robust fusion method, we can efficiently exploit the diversity gain of the multi‐source and channel‐varying signals to improve the Co ...

Developmentally Sensitive Interaction Effects of Genes and the Social Environment on Total and Subcortical Brain Volumes.

PLoS ONE, 2016
Smaller total brain and subcortical volumes have been linked to psychopathology including attention-deficit/hyperactivity disorder (ADHD). Identifying mechanisms underlying these alterations, therefore, is of great importance. We investigated the role of

A Rare Presentation of Hyperphagia and Parasomnias Associated With Chromosome 4q Deletion: A Case Report

Case Reports in Psychiatry, Volume 2025, Issue 1, 2025.
Background: Chromosome 4q deletion is a rare genetic disorder affecting an estimated 1 out of 100,000 people. It is characterized by microdeletions of the long arm of chromosome 4 with variable clinical presentations including heart defects, craniofacial and skeletal abnormalities, short stature, and developmental delays.

Distribution of alleles of DRD4 and DAT1 genes of the dopaminergic system in the mixed Chilean population Distribución de alelos de los genes DRD4 y DAT1 del sistema dopaminérgico en la población mixta de Santiago de Chile [PDF]

, 2003
Background: Genes for dopamine receptor DRD4 and dopamine transporter DAT1 are highly polymorphic. Two alleles of these genes, namely the DRD4.7 and the DAT1*9 are frequently associated to the attention deficit disorder with hyperactivity. In Europe, the

The dopaminergic midbrain participates in human episodic memory formation: Evidence from genetic imaging

, 2006
Recent data from animal studies raise the possibility that dopaminergic neuromodulation promotes the encoding of novel stimuli. We investigated a possible role for the dopaminergic midbrain in human episodic memory by measuring how polymorphisms in ...

The Dopamine Transporter Gene (DAT1) Polymorphism is Associated with Premature Ejaculation

The Journal of Sexual Medicine, 2010
ABSTRACTIntroductionPrevious research has suggested brain dopamine (DA) neurotransmission to be involved in the control of ejaculation. Furthermore, previous studies indicate a partly hereditary background to premature ejaculation.AimTo investigate whether the dopamine transporter gene (DAT1) polymorphism is associated with premature ejaculation ...

Membrane-bound catechol-O-methyl transferase in cortical neurons and glial cells is intracellularly oriented

Frontiers in Psychiatry, 2010
Catechol-O-methyl transferase (COMT) is involved in the inactivation of dopamine in brain regions in which the dopamine transporter (DAT1) is sparsely expressed.

The role of the dopamine transporter DAT1 genotype on the neural correlates of cognitive flexibility

European Journal of Neuroscience, 2010
AbstractCognitive 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 ...

Association of adult attention deficit hyperactivity disorder with dopamine transporter gene, dopamine D3 receptor, and dopamine D4 receptor gene polymorphisms

Psychiatry and Clinical Psychopharmacology, 2021
Objective: Attention deficit hyperactivity disorder (ADHD) is a developmental disorder which is characterized by inattention, impulsiveness, and hyperactivity. The etiology of ADHD is not completely understood, but it is well known that the disorder has
