The CRISPR-Cas9 has revolutionized the field of molecular biology, medical genetics and medicine. The technology is robust, facile and simple to achieve genome targeting in cells and organisms. However, to propagate these nucleases for therapeutic application, the on-target specificity is of paramount importance. Although the binding and cleavage of off-target sites by Cas9 is issue of concern, however the specificity of CRISPR technology is greatly improved in current research employing the use of engineer nucleases, improved gRNA selection, novel Cas9 orhtologs and the advancement in methods to detect and screen off-target sites and its effects. Here we summarize the advances in this state-of-the-art technology that will equip the genome editing tools to be applied in clinical research. The researcher should optimize these methods with emphasize to achieve perfection in the specificity read more ...
