mtgRNA-db: An annotated database of multi-target CRISPR-Cas9 guide-RNAs in the human genome

CRISPR-Cas9 guide-RNA design tools can be used to identify guide-RNAs that target single human genomic loci. However, these approaches limit their effect to a single locus. Here, we generate a database of potential individual guide-RNAs that target multiple sites in the genome at once. All guide-RNAs in this database are curated with on- and off-target quantification and enrichment scores for genomic elements such as gene elements, regulatory elements, repetitive elements, and transcription factor motifs. This tool enables rationale mass targeting of genomic loci with a single guide for functional studies. We created a web-app for user-friendly guide-RNA selection (https://modreklab.shinyapps.io/guiderna/).
