基因组编辑技术的飞速发展,尤其是近年来CRISPR/Cas9基因组编辑体系的出现,使得研究人员能高效地在细胞系和动物模型中对基因组进行精确编辑。基于基因组编辑技术的各种实验研究平台被相继开发,包括通过在细胞系中引入疾病相关突变位点建立疾病模型,通过高通量筛选寻找导致肿瘤耐药性的突变基因,通过体内原位靶向致病基因并修改突变进行基因治疗等。这些基因组编辑技术研究平台极大推动了精准医学研究领域的发展。本文对基因组编辑技术在精准医学领域的基础研究、转化应用、目前存在的问题以及未来发展的方向进行了讨论。

The emergence of genome editing tools, such as the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) system, has enabled researchers to achieve somatic and germline genomic manipulations in cell lines and model organisms. Within a couple of years, genome editing is now being rapidly developed for multiple applications and widely used in biomedical researches, including creation of disease models with desired genetic mutations, screening in a high-throughput manner for drug resistance genes, and making appropriate editions to genes in vivo for disease treatment. All these applications have been facilitating the development of precision medicine research. In this review, we describe the use of genome editing technologies for a variety of research and translational applications in the precision medicine field. We also highlight some of the existing limitations or challenges as well as future directions.
