Abstract

Recombinant DNA technology, one of the major controversial areas of biological research in the late 1970s, is now rapidly providing new avenues for diagnosis and treatment. With the early recognition that extensive DNA variation exists in human populations, molecular genetic diagnosis of a variety of common hereditary diseases has become a reality. Recent identification of the location of the gene (or genes) for cystic fibrosis and adult polycystic kidney disease, and characterization of the region of the Duchenne muscular dystrophy gene will lead us towards a better understanding of the basic defects in these diseases. The identification of large multi-generation families with genetic diseases that are useful for identifying gene locations will require the co-operative participation of clinicians, medical geneticists and molecular biologists.

摘要

重组 DNA 技术是 20 世纪 70 年代后期生物学研究中最具争议的领域之一,如今它正在迅速为诊断和治疗开辟新途径。由于人们很早就认识到人类群体中存在广泛的 DNA 变异,因此对各种常见遗传性疾病的分子遗传诊断已成为现实。最近确定了囊性纤维化和成人多囊肾病的基因(或基因)位置,并对杜兴氏肌肉营养不良症基因区域进行了描述,这将使我们更好地了解这些疾病的基本缺陷。鉴定具有遗传疾病的大型多代家族对于鉴定基因位置非常有用,这需要临床医生、医学遗传学家和分子生物学家的共同合作。
