Genetic variants in the oxytocin receptor (OTR) have been linked to distinct social phenotypes, psychiatric disorders and brain volume alterations in adults. However, to date, it is unknown how OTR genotype shapes prenatal brain development and whether it interacts with maternal prenatal environmental risk factors on infant brain volumes. In 105 Finnish mother-infant dyads (44 female, 11-54 days old), the association of offspring OTR genotype rs53576 and its interaction with prenatal maternal anxiety (revised Symptom Checklist 90, gestational weeks 14, 24, 34) on infant bilateral amygdalar, hippocampal and caudate volumes were probed. A sex-specific main effect of rs53576 on infant left hippocampal volumes was observed. In boys compared to girls, left hippocampal volumes were significantly larger in GG-homozygotes compared to A-allele carriers. Furthermore, genotype rs53576 and prenatal maternal anxiety significantly interacted on right hippocampal volumes irrespective of sex. Higher maternal anxiety was associated both with larger hippocampal volumes in A-allele carriers than GG-homozygotes, and, though statistically weak, also with smaller right caudate volumes in GG-homozygotes than A-allele carriers. Our study results suggest that OTR genotype enhances hippocampal neurogenesis in male GG-homozygotes. Further, prenatal maternal anxiety might induce brain alterations that render GG-homozygotes compared to A-allele carriers more vulnerable to depression.

婴儿催产素受体基因的变异调节婴儿海马体积与性和产前母亲焦虑相关

催产素受体 (OTR) 的遗传变异与成人不同的社会表型、精神疾病和脑容量改变有关。然而,迄今为止,尚不清楚 OTR 基因型如何影响产前大脑发育以及它是否与母体产前环境风险因素对婴儿脑容量的相互作用。在 105 名芬兰母婴二人组(44 名女性,11-54 天大)中,后代 OTR 基因型 rs53576 的关联及其与婴儿双侧杏仁核的产前母亲焦虑的相互作用(修订后的症状清单 90,妊娠周 14、24、34) ,海马和尾状核体积进行了探测。观察到 rs53576 对婴儿左侧海马体积的性别特异性主效应。男孩与女孩相比,GG 纯合子的左侧海马体积明显大于 A 等位基因携带者。此外,基因型 rs53576 和产前母亲焦虑在右侧海马体积上显着相互作用,而与性别无关。较高的母体焦虑与 A 等位基因携带者的海马体积大于 GG 纯合子有关,尽管在统计学上较弱,但与 A 等位基因携带者相比,GG 纯合子的右尾状体体积更小。我们的研究结果表明,OTR 基因型增强了雄性 GG 纯合子的海马神经发生。此外,与 A 等位基因携带者相比,产前母亲的焦虑可能会导致大脑发生改变,从而使 GG 纯合子更容易患上抑郁症。较高的母体焦虑与 A 等位基因携带者的海马体积大于 GG 纯合子有关,尽管在统计学上较弱,但与 A 等位基因携带者相比,GG 纯合子的右尾状体体积更小。我们的研究结果表明,OTR 基因型增强了雄性 GG 纯合子的海马神经发生。此外,与 A 等位基因携带者相比,产前母亲的焦虑可能会导致大脑发生改变,从而使 GG 纯合子更容易患上抑郁症。较高的母体焦虑与 A 等位基因携带者的海马体积大于 GG 纯合子有关,尽管在统计学上较弱,但与 A 等位基因携带者相比,GG 纯合子的右尾状体体积更小。我们的研究结果表明,OTR 基因型增强了雄性 GG 纯合子的海马神经发生。此外,与 A 等位基因携带者相比,产前母亲的焦虑可能会导致大脑发生改变,从而使 GG 纯合子更容易患上抑郁症。
