Clinical validation study of RAKSET-B, a multiple detection kit for BRAF and RAS gene mutations in colorectal cancer

Primary outcome(s): BRAF gene mutation* - Overall concordance rate, positive concordance rate, and negative concordance rate of BRAF gene mutations between standard genetic testing such as sanger sequencing and RASKET-B kit RAS gene mutation** - Overall concordance rate, positive concordance rate, and negative concordance rate of RAS gene mutations between MEBGEN RASKET KIT (an established in vitro diagnostic (IVD) kit for detecting RAS mutations) and RASKET-B kit *BRAF gene mutation codon 600 (p.V600E) **RAS gene mutation codon 12, 13, 59, 61, 117, 146
