Abstract: Abstract: Whole-genome screen is a powerful tool for genetic studies and can be used to identify novel genes that contribute to special biological phenotypes. Recently, a high-throughput and efficient screen based on CRISPR/Cas9 genome-editing has been applied to study the mechanisms underlying human diseases and discover new potential drug targets. Meanwhile, CRISPR/Cas9 screen can specifically target promoters, enhancers and long non-coding RNAs to uncover new class of cis-regulatory factors or non-protein coding genes. In addition, a combination of CRISPR/Cas9 screen and single cell RNA sequencing allows us to capture transcriptome variation and genetic interactions in detail.
