用基因置换的方法直接检查异常基因、发现遗传病的“DNA 诊断(基因诊断)”,和给遗传病患者编入正常基因的“基因治疗”技术正在发展,使人类的操作进入一个越来越危险的领域,并提出一些新的伦理学问题。在东京由疑难病研究财团主持召开的疑难病的遗传学新途径国际专题座谈会,约有150名国内外学者参加,围绕上述问题进行了认真的讨论。在发病前发现遗传性疾病DNA 诊断:遗传基因异常引起的疾病有显性和隐性两种。通常每组基因都有来自父和母的基因。其中无论哪一方的异常均可致病者为显性,而必须双方的基因均异常方可致病者则为隐性。遗传基因异常有各种各样的方式,大致可分为能 A direct examination of abnormal genes using gene replacement has led to the discovery that “DNA diagnostics (genetic diagnostics)” of genetic diseases and “gene therapy” technologies that code for normal genes in hereditary diseases are evolving to move human operations into an increasingly Dangerous areas, and put forward some new ethical issues. About 150 international and domestic scholars attended the symposium on new ways of genetics for difficult diseases under the auspices of the Disease Research Foundation in Tokyo, and discussed them seriously. Found in the incidence of genetic disease before DNA diagnosis: Genetic abnormalities caused by disease are dominant and recessive in two. Normally each group of genes has genes from the parent and the mother. No matter which side of the abnormalities can be pathogenic for the dominant, and both genes must be abnormal before the disease is recessive. There are a variety of ways genetic abnormalities can be broadly divided into
