一、遗传病的治疗遗传病曾被一些人认为是“不治之症”,近年来,由于医学遗传学的发展,对遗传病的发病原理有了一定的认识,在诊断、治疗和预防上都提出了一些有效括施,为根治遗传病开辟了光辉的前景。图1表示一些单基因遗传病的发病过程。人体中任何遗传性状的形成都需要经过一系列的代谢过程才能实现,代谢过程的每一步都由基因控制的酶来催化。当某一基因发生突变后,由于遗传信息的改变,经过错误的表达(转录和翻译),由此基因所控制的 First, the treatment of genetic disease Genetic disease was considered by some people as “incurable disease” in recent years, due to the development of medical genetics, the pathogenesis of genetic diseases have a certain understanding, in the diagnosis, treatment and prevention are Put forward some effective measures and opened up a brilliant prospect for the cure of genetic diseases. Figure 1 shows the pathogenesis of some single-gene genetic diseases. The formation of any genetic trait in the body requires a series of metabolic processes, each of which is catalyzed by a gene-controlled enzyme. When a gene mutation occurs, due to changes in genetic information, after the wrong expression (transcription and translation), which gene-controlled
