INTERPRETATION: Similar to molecular genetic studies, we showed evidence that schizophrenia and bipolar disorder partly share a common genetic cause. These results challenge the current nosological dichotomy between schizophrenia and bipolar disorder, and are consistent with a reappraisal of these disorders as distinct diagnostic entities.

解释：类似于分子遗传学的研究证实了精神分裂症和双相情感障碍具有部分共同的疾病基因，对当前疾病分类学上这两类疾病的独立分类提出了挑战，有必要对它们显著的和特征性的本质再次进行认识。
