350 carefully selected schizophrenic probands and their parents and siblings were diagnosed according to three different clinical classifications, and a multiple-threshold analysis was carried out within the framework of the multifactoral model of inheritance. The results suggest that of the three classification systems, Leonhard's and Sneshnevsky's nosological system delineates relatively homogeneous subtypes from the clinical and genetic point of view, pointing to the promise these nosological systems have for the planning of future research in psychiatric genetics.
根据三种不同的临床分类对350名精心挑选的精神分裂症先证者及其父母和兄弟姐妹进行了诊断，并在多因素遗传模型框架内进行了多阈值分析。结果表明，在这三种分类系统中，莱昂哈德和斯涅什涅夫斯基的疾病分类系统从临床和遗传学角度划分出了相对同质的亚型，这表明这些疾病分类系统在规划未来精神遗传学研究方面具有前景。
