Abstract excerpt

Variation in the μ-opioid receptor gene has been associated with early social behavior in mice and rhesus macaques. The current study tested whether the functional OPRM1 A118G predicted various indices of social relations in children. The sample included 226 subjects of self-reported European ancestry (44% female; mean age 13.6, SD=2.2) who were part of a larger representative study of children aged 9-17 years in...
