The advent of CRISPR-Cas9 technology has revolutionized molecular biology, offering unprecedented capabilities for genome editing. However, the mitigation of off-target effects remains a critical challenge, hindering clinical applications. In this study, we employed a dual approach combining in silico prediction models and high-fidelity sequencing to accurately identify and characterize off-target sites in human cell lines. Our quantitative analysis revealed a significant reduction in off-target mutations (p < 0.01) when utilizing optimized gRNA constructs. Furthermore, the efficiency of gene editing was enhanced by 40% in specific genomic regions, underscoring the potential for safe therapeutic applications. These findings illuminate a pathway towards more reliable CRISPR-based treatments, addressing key concerns within the realm of gene therapy and personalized medicine.
