Central vasopressin receptors and affiliation  

Autism spectrum disorders (ASDs) are characterized by deficits in three core domains: social interaction, communication, and repetitive behaviors. Recent data suggests that while all three behavioral domains are highly heritable, separate genes may contribute independently to variation in each domain. This proposal focuses on the role of the vasopressin V1a receptor (V1aR) in generating diversity in social behaviors in an animal model (prairie voles) and humans. The V1aR plays a critical regulatory role in several behaviors in the social domain, including social recognition, parental care, and social bonding. The study will examine variations in expression of the AVPR1A gene (which encodes the V1aR), look for polymorphisms (changes in DNA sequence), and determine the gene's role in variation in social behavior of prairie voles. Correlations between polymorphic sites near the AVPR1A gene and phenotypic behavioral measures will then be examined in human subjects. Results from these studies will provide important information on the relationship of variation in the V1aR system and social behavior and may lead to therapies specifically targeting the social deficits in autism.
