OBJECTIVES To investigate associations between single nucleotide polymorphisms (SNPs) linked to the oxytocin, To investigate these associations in a large, population-based sample. PATIENTS AND METHODS In all, 1517 male twins and non-twin brothers of twins aged 18-45 years (mean = 26.43; SD = 4.87) A Bayesian linear mixed-effects model, which appropriately controls for between subjects dependence, We corrected for multiple testing using a linkage disequilibrium correlation measure. RESULTS We found a heterozygote effect on one SNP in the oxytocin receptor gene (rs75775), so that individuals Several SNPs in the arginine vasopressin receptor genes had rare or very rare genotypes. This study CONCLUSIONS Our results regarding the oxytocin receptor polymorphisms support previous studies that indicate a Oxytocin receptor genes are, for example, unlikely suitable targets for pharmacogenetic intervention Rare variants in arginine vasopressin receptor genes may have significant effects on premature
