现代医学研究表明,血友病、色盲、精神分裂症、痴呆症等许多疾病都与遗传有关;原发性高血压病、糖尿病和某些癌症有家族聚集现象。有研究报告指出,父母都是高血压病患者,其30岁以上的子女患高血压病的风险要比其他人高8倍。因此,父母一方或双方患有遗传病或有遗传倾向的疾病,其子女也易患同种疾病或是病态基因的携带者。 Modern medical research shows that many diseases such as hemophilia, color blindness, schizophrenia and dementia are all genetically related. Familial aggregation occurs in essential hypertension, diabetes and certain cancers. A research report pointed out that parents are hypertensive patients, their children over the age of 30 suffering from hypertension risk of 8 times higher than others. As a result, one or both parents have genetic or genetic predispositions and their children are also susceptible to the same disease or carriers of pathogenic genes.
