To test the hypothesis that a 44-base-pair insertion/deletion polymorphism in the 5' regulatory region of the serotonin transporter gene (5-HTTLPR) is associated with primary insomnia.
Association study.
Sleep laboratory at the Central Institute of Mental Health, Mannheim, Germany.
157 patients with primary insomnia and 827 healthy controls.
N/A.
We found the short (s-) allele of the 5-HTTLPR to be significantly more frequent in patients suffering from insomnia than in control individuals (47.1% vs. 39.9%: OR = 1.34).
This finding contributes to the understanding of the pathophysiology of primary insomnia and suggests a biological basis between the prevalent comorbidity of primary insomnia and other psychiatric disorders.

关联研究。
德国曼海姆中央心理卫生研究所睡眠实验室。
157 例原发性失眠患者和 827 例健康对照者。
无。
我们发现原发性失眠患者中短(s-)等位基因的频率明显高于对照组(47.1%比 39.9%:OR=1.34)。
这一发现有助于理解原发性失眠的病理生理学,并提示原发性失眠与其他精神障碍普遍共病之间存在生物学基础。
