Alongside this, technologies such as the CRISPR/Cas system have been adapted to enable programmable gene editing in human cells. When combined, CRISPR/Cas gene editing of donor-specific iPSC to generate isogenic cell lines that differ only at specific gene variants provides a powerful model with which to investigate genetic variants associated with diseases affecting many organs, including the brain and eye. Here we describe our optimized protocol for using CRISPR/Cas ribonucleoproteins to edit disease causing gene variants in human iPSCs. We discuss design of crRNAs and homology-directed repair templates, assembly of CRISPR/Cas ribonucleoproteins, optimization of delivery via nucleofection, and strategies for single cell cloning, efficient clone cryopreservation and genotyping for identifying iPSC clones for further characterization.
