Abstract

Serotonin receptor type 2 (5-HTR2A) polymorphism was consistently reported to be related to schizophrenia and some clinical presentations of the disease. The present study aimed at searching for association between 5-HTR2A polymorphism and schizotypic personality traits being considered as recognized phenotype predisposing to schizophrenia. Relationship between these features measured by SPQ-74 and two 5-HTR2A polymorphic loci has been studied in mentally healthy community sample (n = 64). Significant difference was found between AG and GG genotype carriers on No-close-friends scale (t = 2.3; p = 0.03), with GG scoring higher on this item. Also, a trend towards higher scores on this scale (p = 0.08) was observed in women, but not in men, with A2A2 genotype. To a certain extent, the results confirm a hypothesis articulated in the study of G-allele and A2-allele relation to interpersonal relationship factor of SPQ-74.
