Colorectal Cancer Mutation Panel (KRAS, PIK3CA, BRAF, NRAS)
Use
This panel detects tumor-associated somatic mutations in KRAS, NRAS, BRAF, and PIK3CA, which are oncogenes associated with colorectal cancer. Mutations in these genes—particularly in KRAS, NRAS, BRAF, and specific exons of PIK3CA—predict diminished response to EGFR-targeted therapies (e.g., cetuximab, panitumumab) and may be associated with more aggressive clinical behavior in metastatic colorectal cancer.
