Methods for detecting off-target effects of CRISPR/Cas9

The CRISPR/Cas9 system has emerged as a revolutionary tool for gene editing, widely used in the biomedical field due to its simplicity, efficiency, and cost-effectiveness. However, evidence suggests that CRISPR/Cas9 can induce off-target effects, leading to unintended mutations that may compromise the precision of gene modifications. Consequently, predicting，detecting and evaluating these off-target effects is crucial for optimizing the accuracy and reliability of CRISPR/Cas9 system. This paper provides an overview of the various methodologies and strategies, used or to be used for identifying off-target effects in CRISPR/Cas9-based genome editing, offering insights to improve the precision and safety of CRISPR applications in research and therapeutics.
