Philadelphia, PA, April 29, 2009 A growing body of basic animal research and studies of abused and neglected children provide a strong basis of support for the hypothesis that individuals with particular genotypes are at greater risk for depression, anxiety disorders, and problems with the abuse of alcohol and other substances. These gene-by-environment interactions are so powerful that some might assume that these genotypes identify people who are predestined to negative life outcomes.
However, a new study in the May 1st issue of Biological Psychiatry (http://www.elsevier.com/locate/biopsychiat), published by Elsevier, challenges this view. Investigators studied infant monkeys from four different rearing conditions to examine how social context and different forms of early adversity interact with genotype to influence behavior.
