5-HT1A polymorphism and self-transcendence in mood disorders

Authors


Abstract

Recently, an association between serotonin 1A receptor binding potential and self-transcendence scores at the temperament and character inventory (TCI) has been reported. We tested involvement of 5-HT1A gene in this trait, in a sample of 40 remitted mood disorder patients. Subjects with the 5-HT1A*C/C genotype showed significantly lower scores at the total self-transcendence and at the sub-scales of transpersonal identification and spiritual acceptance. Our preliminary results further support the involvement of the serotoninergic pattern in the self-transcendence character trait. © 2005 Wiley-Liss, Inc.
