Family study data on unipolar affective illness are analyzed by multiple threshold models of inheritance that incorporate sex effect. In these models males and females share a common genetic-environmental liability, but the less prevalent sex, i.e., males, has a higher genetic threshold for the disorder. Neither single major locus (SML) nor multifactorial-polygenic (MFP) transmission can account for the sex differences in the morbid risk for unipolar disorder. The implications for genetic research in affective disorders are discussed.
对单相情感障碍的家系研究数据，采用纳入性别效应的多阈值遗传模型进行分析。在这些模型中，男性和女性具有共同的遗传 - 环境易感性，但发病率较低的性别，即男性，患该疾病的遗传阈值更高。单一位点（SML）遗传和多因素 - 多基因（MFP）遗传均无法解释单相情感障碍发病风险中的性别差异。文中讨论了这些发现对情感障碍遗传研究的意义。
