The OncoCarta panel includes assays for most colon cancer mutations in the clinically relevant genes, BRAF (99%), KRAS (98%), and PIK3CA (78%), and in addition contains assays for other cancer mutations in genes that intersect with the same pathways as that of KRAS, BRAF, and PIK3CA, such as AKT1, EGFR, HRAS, NRAS, MET and others. Here, PIK3CA is linked to cancer.
