KIT V560del KIT over exp | thymic carcinoma | predicted - sensitive | Imatinib | Case Reports/Case Series | Actionable | In a clinical case report, a patient with metastatic thymic carcinoma harboring KIT V560del with KIT over expression initially demonstrated stable disease and reduction in metastatic lesions following treatment with Gleevec (imatinib), but progressed after 6 months (PMID: 15201427). | 15201427 |
KIT V560del KIT V654A | Advanced Solid Tumor | sensitive | Nilotinib | Preclinical - Cell culture | Actionable | In a preclinical study, Tasigna (nilotinib) inhibited proliferation of transformed cells expressing a KIT V560del/V654A double mutation in culture (PMID: 17699867). | 17699867 |
KIT V560del KIT N822K | gastrointestinal stromal tumor | predicted - resistant | Imatinib | Case Reports/Case Series | Actionable | In a clinical case study, a patient with gastrointestinal stromal tumor harboring KIT V560del progressed following an initial response to Gleevec (imatinib), and was found to have acquired the secondary resistance mutation KIT N822K (PMID: 18294292). | 18294292 |
KIT K558N KIT V560del | gastrointestinal stromal tumor | predicted - sensitive | Imatinib | Case Reports/Case Series | Actionable | In a clinical case study, Gleevec (imatinib) treatment led to a partial response in a patient with gastrointestinal stromal tumors harboring KIT K558N and KIT V560del (reported as KIT V559del), with a progression-free survival of 23.4 months and an overall survival of 54.7 months (PMID: 18294292). | 18294292 |
