It is reported on 2 cases of the XYY chormosomal constitution. The patients were comparable only with respect to some somatic deviations. Age at manifestation of psychic abnormalities as well as the degree of deviation of behaviour were rather different. One patient got his psychic traumatization mainly in early childhood where as the other suffered from a more puberal conflict. Genetic disposition may be the basic cause of the psychological abnormalities. Yet, the degree of deviation seems to be influenced mainly by environmental factors.
报告了2例XYY染色体构成的病例。患者仅在一些躯体偏差方面具有可比性。精神异常出现时的年龄以及行为偏差程度有很大差异。一名患者主要在幼儿期遭受精神创伤，而另一名患者则患有更青春期的冲突。遗传倾向可能是心理异常的根本原因。然而，偏差程度似乎主要受环境因素影响。
