A novel cell line generated using the CRISPR/Cas9 technology as universal quality control material for KRAS G12V mutation testing

Background KRAS mutations are the key indicator for EGFR monoclonal antibody‐targeted therapy and acquired drug resistance, and their accurate detection is critical to the clinical decision‐making of colorectal cancer. However, no proper quality control material is available for the current detection methods, particularly next‐generation sequencing (NGS). The ideal quality control material for NGS needs to provide both the tumor mutation gene and the matched background genomic DNA, which is uncataloged in public databases, to accurately distinguish germline polymorphisms and somatic mutations.
