Although CRISPR is incredibly useful for generating mutations by NHEJ and generating small mutations with HDR, when it comes to larger scale genome editing, such as replacement of a mouse gene with its human ortholog (greater than 5 kb), it remains to be seen whether CRISPR is as robust as conventional gene targeting.

A few virus particles have learned to circumvent the CRISPR / Cas defense by generating a single point mutation in the PAM sequence, preventing the Cas nucleases from re-identifying it (3).
