In a WT FFPE specimen, the OncoBEAM-TM-RAS-CRC assay detected one p.G12C KRAS mutation (216 mutated signals) in cfDNA that was confirmed by NGS at a low 0.6% allelic frequency (Supplementary Table 3, BEAMing blue box and NGS orange box). The gene discussed is KRAS; the disease is colorectal carcinoma.
