Abstract
- Abstract: Background: Oxytocin is associated with social interaction, trust, and affectivity. Affective temperaments are traits based on Kraepelin''s typological definition of the “fundamental states” of manic-depressive illness. These states can be measured by the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire version (TEMPS-A). The objective of this study is to assess the association between oxytocin receptor gene (OXTR) polymorphisms and affective temperaments. Methods: Participants consisted of 493 genetically unrelated, non-clinical Japanese subjects (307 males and 186 females). The Mini-International Neuropsychiatric Interview (MINI) was used to screen and exclude those who had a lifetime diagnosis of schizophrenia or other psychotic disorders. Fifteen OXTR tag single nucleotide polymorphisms (SNPs) were genotyped using TaqMan® or direct sequencing. The Haploview 4.1. software determined the haplotype block structure. Haplotype-based quantitative trait association analysis with Bonferroni correction using PLINK 1.06 software was used to assess the association between haplotypes and the following affective temperaments: depressive, cyclothymic, hyperthymic, irritable, and anxious. Results: Two haplotype blocks were identified on the OXTR. The depressive temperament was significantly associated with the most frequent haplotype GGGTGTC (rs11131149/rs2243370/rs2243369/rs13316193/rs2254298/rs2268493/rs2268491) (corrected P <0.05). Limitations: This study consisted of participants from a corporation and the effect sizes were small. Conclusions: The findings suggest that an OXTR haplotype is associated with a discrete depressive temperament. Clarification of the biological basis of this temperamental trait may help to elucidate the pathophysiology of depressive disorder. [Copyright &y& Elsevier]
