Figure 1From: Simultaneous identification of 36 mutations in KRAS codons 61and 146, BRAF, NRAS, and PIK3CAin a single reaction by multiplex assay kit Associations among KRAS , BRAF , NRAS , and PIK3CA mutations. KRAS codon 12 and 13, KRAS codon 61 and 146, BRAF , and NRAS mutations were mutually exclusive. Only PIK3CA Exon 9 and 20 mutations overlapped KRAS codon 12 and 13 and BRAF mutations.Back to article page
