The incidence of BPD in patients with the G,G variant of the HTR1A gene (12 out of 60; 20.0%) was 1.75 times the incidence of BPD in patients with the C,C variant (eight out of 70; 11.4%) or the C,G variant of this gene (13 out of 136; 9.6%).P-values, odds ratios, and associated 95% confidence intervals (CIs) for all parameters considered in uncontrolled logistic regression models are summarized in Table 2. This evidence concerns the gene HTR1A and Borderline personality disorder.
