Overall, Daniels et al. 12 showed that - compared to children receiving placebo - the group of children receiving oxytocin did not display stronger improvements in parent-reported social functioning (assessed as primary behavioural outcome using the Social Responsiveness Scale) or repetitive behaviours, attachment or anxiety, although the combination of oxytocin administration with psychosocial treatment might suggest a synergetic effect12. The gene discussed is OXT; the disease is Anxiety.
