DRD4 7-repeat polymorphism moderates the association between maternal unresolved loss or trauma and infant disorganization.

Attachment & human development - 1 Dec 2006

Van Ijzendoorn Marinus H, Bakermans-Kranenburg Marian J

Abstract excerpt

Previous studies have related attachment disorganization in children to either dopamine D4 receptor polymorphisms or maternal unresolved loss or trauma and frightening or anomalous parenting. In this study it was examined whether the interaction between genetic (DRD4 7-repeat and -521 C/T) and environmental risk factors (maternal unresolved loss/trauma and maternal frightening behavior) was associated with infant...
