The authors perform saturation mutagenesis of genomic regions in their native endogenous chromosomal context by using CRISPR/Cas9 RNA-guided cleavage and multiplex homology-directed repair; its utility is demonstrated by measuring the effects of hundreds to thousands of genomic edits to BRCA1 and DBR1 on splicing and cellular fitness, respectively.
