| MAP2K1 K57N | colorectal cancer | resistant | Panitumumab | Case Reports/Case Series | Actionable | In a retrospective analysis, two patients with metastatic RAS/BRAF wild-type colorectal cancer demonstrated progressive disease following treatment with Vectibix (panitumumab) and via analysis of archived pretreatment tumor biopsy samples and post-progression liquid biopsy both were found to harbor MAP2K1 K57N (PMID: 36419886). | 36419886 |
| MAP2K1 K57N | colorectal cancer | resistant | Panitumumab | Preclinical | Actionable | In a preclinical study, colorectal cancer cell lines expressing MAP2K1 K57N were insensitive to Vectibix (panitumumab) in culture (PMID: 26644315). | 26644315 |
