One prominent example is the CancerSeek test, developed by Ludwig Cancer Research at Johns Hopkins University, which employed a panel of mutations at 2001 locations across 16 cancer‐associated genes (TP53, GNAS, PPP2R1A, HRAS, KRAS, AKT1, PTEN, FGFR2, CDKN2A, BRAF, EGFR, APC, FBXW7, PIK3CA, CTNNB1, and NRAS) to detect eight cancer types [15]. The gene discussed is CTNNB1; the disease is cancer.
