Previous studies have indicated that alexithymia is associated with the availability of serotonin in the brain and with the insecure attachment orientation. Inspired by the finding that the receptor 5-HT1A modulates the level of serotonin in the brain, this study investigated to what extent a polymorphism (C-1019G, rs6295) of 5-HT1A gene modulates individuals' alexithymic characteristics and attachment orientation in 504 Chinese Han people. Results showed significantly higher total scores on the 20-item Toronto Alexithymia Scale (TAS-20) for individuals carrying the CG/GG genotype than for individuals carrying the CC genotype. Specifically, individuals with the CG/GG genotype reported greater difficulty in identifying own feelings than individuals with the CC genotype. Results also showed that individuals carrying the CG/GG genotype seemed to be less comfortable with having close relationships to others than individuals with the CC genotype. These findings provide the first evidence for the link between 5-HT1A and the development of alexithymic characteristics and attachment orientation.
