使用下一代测序来鉴定与CD4启动子附近CAS9诱导的双链断裂修复相关的突变

Executive Industry Relevance

Targeted identification of mutations arising from double-strand break (DSB) repair is critical for de-risking genome editing and understanding genomic instability mechanisms in drug discovery. This Cas9/sgRNA-directed next generation sequencing (NGS) workflow enables precise, locus-specific mutation profiling, supporting predictive confidence in DNA repair pathway interrogation. The approach streamlines early discovery and translational research by reducing computational burden and enabling scalable, cost-effective analysis of repair fidelity under diverse experimental conditions.

Strategic Applications in Biopharma R&D

Early Discovery & Target Validation

• Enables mechanistic de-risking by directly linking DSB repair outcomes to specific genetic or environmental perturbations.
• Supports functional target validation by quantifying mutation types and frequencies at defined loci.
• Facilitates portfolio triage by revealing repair pathway vulnerabilities and mutagenic potential of candidate targets or factors.

Screening & Assay Development

• Prepares validated cell-based systems for high-confidence assessment of DNA repair modulators.
• Delivers reproducible, quantitative mutation readouts for assay standardization and downstream screening.
