But the approach of introducing a corrected gene holds promise for all nations as researchers continue to refine and improve the therapy.

但是，随着研究人员不断完善和改进治疗方法，引入校正基因的方法对所有国家都是有希望的。

Rather than editing the gene out, Dr. John Tisdale says his team added a copy of the normal correct gene which produced healthy blood cells.

约翰·蒂斯代尔博士说，他的研究小组没有对病变基因进行编辑，而是添加了一份正常的正确基因的副本，该基因可以产生健康的血细胞。

By targeting and correcting the faulty gene, it might be possible to alleviate, or even completely eradicate, the symptoms of these diseases.

通过瞄准和纠正有缺陷的基因，有可能减轻甚至完全根除这些疾病的症状。

It's becoming a reality to correct defective genes in patients with inherited diseases, such as severe combined immunodeficiency, you may know it as the bubble boy syndrome, and sickle cell anemia.

纠正遗传性疾病患者的缺陷基因正在成为现实，例如严重的联合免疫缺陷， 你可能知道它是泡泡男孩综合症和镰状细胞性贫血。
