A Comparative Analysis of Gene Editing Techniques: CRISPR-Cas9 Versus Base Editing in the Context of Genomic Medicine

Abstract

The advent of gene editing technologies has marked a transformative era in genomic medicine. This study systematically compares CRISPR-Cas9 and base editing approaches, focusing on their precision, efficiency, and potential off-target effects. Utilizing an experimental framework involving human cell lines, we utilized high-throughput sequencing to determine editing accuracy and assessed phenotypic outcomes through CRISPR interference assays. Our findings demonstrate that while both techniques offer substantial promise, base editing shows a marked improvement in reducing off-target mutations, with an error rate of less than 0.1%, compared to approximately 3% for CRISPR-Cas9. Moreover, the application of base editing resulted in enhanced therapeutic outcomes in targeted genetic disorders. This research provides critical insights for future applications in clinical settings, paving the way for improved gene therapies. This comparative analysis underlines the necessity for continued research into the optimization of these methodologies, ensuring their safe and effective application in treating human diseases.
