KRAS/NRAS Mutations Detection KitDetection of 19 KRAS mutations (exons 2, 3 and 4) and 13 NRAS mutations (exons 2, 3 and 4)RAS protein is a GTPase and one of the key molecules in the downstream signaling pathway of epidermal growth factor receptor (EGFR). These pathways control cell proliferation, differentiation and apoptosis. Frequency of KRAS and NRAS mutations in colorectal cancer are 36~40% and 1~6% respectively. Most frequent mutations are in exons 2, 3 and 4.RAS mutation is predictive of a very poor response to cetuximab (Erbitux®) and panitumumab (Vectibix®) therapy in colorectal cancer (CRC).[1] The most reliable way to predict whether a colorectal cancer patient will respond to one of the EGFR-inhibiting drugs is to test for activating mutations in the RAS gene.A number of large studies [2][3] have shown that cetuximab has significant efficacy in mCRC patients with RAS wild-type tumors. NCCN clearly indicates that all patients with metastatic colorectal cancer should be determined of tumor RAS (KRAS/NRAS) gene status. Patients with any known KRAS or NRAS mutation should not be treated with either cetuximab or panitumumab. [4]References:1) Lièvre et al. (2006). Cancer Res. 66 (8): 3992–5.2) Bokemeyer et al, (2009).

V1.2015Intended UseCE marked for IVD use in Europe.Technological PrinciplesThe kit uses novel, patented primers and probes to detect mutations in a real-time PCR assay.The mutant DNA is amplified accurately by the specific primers, and detected by the novel probes.Highly Specific primers and probes, and a highly validated procedure based on Taq DNApolymerase contribute to outstanding assay sensitivity and selectivity.The AmoyDx® KRAS/NRAS Mutations Detection Kit is a real-time PCR test intended for qualitative detection of 19 KRAS mutations(exons 2, 3 and 4) and 13 NRAS mutations(exons 2, 3 and 4).19 KRAS and 13 NRAS mutations detected by the panel:
