Serotonergic neurotransmission has been implicated in suicidal behavior, including inconsistent results concerning the serotonin transporter promoter polymorphism (5-HTTLPR). Here, we analyzed the 5-HTTLPR in suicide attempters (n=85). Comparing the presence of SS with SL+LL genotypes showed a significantly higher prevalence of the SS genotype in suicide attempters with high medical damage scores (chi2=9.054, df=1, p=0.0026). The results suggest that the S-allele may predispose for suicidal behavior characterized by high determination.
血清素能神经传递与自杀行为有关，包括血清素转运体启动子多态性（5-HTTLPR）方面的结果不一致。在此，我们分析了自杀未遂者（n = 85）的5-HTTLPR。比较SS与SL + LL基因型的存在情况，发现在具有高医疗损伤评分的自杀未遂者中，SS基因型的患病率显著更高（χ2 = 9.054，自由度 = 1，p = 0.0026）。结果表明，S等位基因可能易导致以高决心为特征的自杀行为。
