FAAH and Anxiety: Behaviorally, carriers of the A-allele of the FAAH C385 SNP as compared to the CC homozygotes were expected to demonstrate lower anxiety ratings as measured by means of task-related subjective ratings of the State-Trait Anxiety Inventory (STAI), and similarly, based on the findings of previous studies [7], we also predicted A-allele carriers to display lower anxiety ratings than CC individuals on the trait scale.
