psychopathological symptoms

Patterns of DNA methylation at specific loci of the dopamine transporter 1 gene and psychopathological risk in trios of mothers, fathers and children

While accumulating literature is demonstrating the role of the dopamine transporter (DAT) in predicting emotional–behavioural difficulties in adults of at risk populations, only few studies have focused on the possible association between the methylation status of the DAT promoter and the psychopathological risk of mothers, fathers and children in normative samples.

DNA methylation at the DAT promoter and risk for psychopathology. Intergenerational transmission between school-age youths and their parents in a community sample

Background: The effect of gene polymorphisms and promoter methylation, associated with maladaptive developmental outcomes, vary depending on environmental factors (e.g., parental psychopathology). Most studies have focused on 0- to 5-year-old children, adolescents, or adults, whereas there is dearth of research on school-age youths and pre-adolescents.

Children’s DAT1 polymorphism moderates the relationship between parents’ psychological profiles, children’s DAT methylation, and their emotional/behavioral functioning in a normative sample

Parental psychopathological risk is considered as one of the most crucial features associated with epigenetic modifications in o↵spring, which in turn are thought to be related to their emotional/behavioral profiles. The dopamine active transporter (DAT) gene is suggested to play a significant role in a↵ective/behavioral regulation.
