Arginine Vasopressin Gene Variation and Behavioural Inhibition in Children: an Exploratory Study

Behavioural inhibition (BI) refers to a temperamental style of responding to unfamiliar people, objects, contexts and challenging situations with cautious, avoidant and restrained behaviour. Several lines of evidence suggest that variation in the genes of the arginine vasopressin system may be candidate genes for BI. We examined associations between BI and a total of eight single‐nucleotide polymorphisms (SNPs) across the arginine vasopressin ( …
