摘要
目的：探讨精神分裂症与遗传学的关系．方法：随机抽取门诊和住院确诊为精神分裂症的100份病例，将其一级亲属的患病状况进行登记．以性别、年龄、人数与患者相同的健康人群一级亲属作为对照．计算精神分裂症的遗传度．结果：17～40岁发病者占73%．因此可将此年龄段视为精神分裂症患病的危险年龄，精神分裂症的遗传度为70.85%．结论：精神分裂症的易感性和家族聚集性主要是由遗传因素决定的，但环境因素对精神分裂症的发病也有一定的影响，属于多基因道传．
Objective ： To study the relationship between schizophrenia and genetics. Methods ：100 cases with schizophrenia by clinic and hospital diagnosis were collected randomly, Register the patient hood of their first-degree relatives and make the ones of healthy population which had the same gender,age and numbers in control, then calculate the heritability of schizophrenia. Results： Patients aged 17-40 is 73 %. so this age group was regarded as risk stage of schizophrenic patients.the heritability of schizophrenia is 70. 85 %. Conclusion.. Schizophrenic susceptibility and family accumulation were mainly determined by genetic factors, however environmental factors also had some influence on the cause of schizophrenia. The schizophrenia is polygenic inheritance.
