Use of the Representative Base Editing Tool Target-AID to Introduce Pathogenic Mutations into Mice.

Base editing technology is a modified CRISPR/Cas system that directly introduces point mutations into targeted genomic regions without causing double-stranded DNA breaks. Target-AID (activation-induced cytidine deaminase) is a representative base editing tool and may serve as a potent option to create genetically modified animals that harbor disease-causing pathogenic point mutations. In this chapter, I describe the basic protocol used to introduce disease-relevant pathogenic mutations into mice by Target-AID.
