Gene Variant Descriptions | BRAF L597Q lies within the protein kinase domain of the Braf protein (UniProt.org). L597Q results in activation of Braf as indicated by increased phosphorylation of Mek and Erk in cell culture (PMID: 22798288) and induces cell proliferation and cell viability in culture (PMID: 29533785). |

---|---|---|---|---|---|---|---|
BRAF L597Q | colon adenocarcinoma | predicted - sensitive | Trametinib | Preclinical - Patient cell culture | Actionable | In a preclinical study, Mekinist (trametinib) inhibited growth of tumor cells derived from the metachronous para-aortal lymph node metastasis harboring BRAF L597Q, which was resected from a patient with colon adenocarcinoma (PMID: 31704811). | 31704811 |
BRAF L597Q | melanoma | predicted - sensitive | Trametinib | Case Reports/Case Series | Actionable | In a Phase II trial, Mekinist (trametinib) treatment resulted in an objective response rate of 33% (3/9, all partial responses) and a median progression-free survival (PFS) of 7.3 months in melanoma patients harboring BRAF fusions or non-V600 BRAF mutations, including a partial response with a tumor reduction of 38% and PFS ongoing 8.3 months in a patient harboring BRAF L597Q (PMID: 33861486; NCT02296112). | 33861486 |
BRAF L597Q | melanoma | predicted - sensitive | Trametinib | Case Reports/Case Series | Actionable | In a retrospective analysis, first-line treatment with Mekinist (trametinib) resulted in a partial response lasting 6.2 months in a melanoma patient harboring BRAF L597Q, with 33% tumor shrinkage (PMID: 24933606). | 24933606 |
BRAF L597Q | Advanced Solid Tumor | resistant | Vemurafenib | Clinical Study - Cohort | Actionable | In a Phase II trial (MyPathway), Zelboraf (vemurafenib) treatment resulted in an objective response in only 4% (1/23) of patient with advanced solid tumors harboring non-V600 BRAF mutations, 1 of the non-responding patients harbored BRAF L597Q (PMID: 29320312; NCT02091141). | 29320312 |
BRAF L597Q | Advanced Solid Tumor | resistant | Vemurafenib | Preclinical - Cell culture | Actionable | In a preclinical study, Zelboraf (vemurafenib) did not inhibit MEK and ERK activation in transformed cells over expressing the constitutively dimerized BRAF L597Q (PMID: 26343582). | 26343582 |
BRAF L597Q | colon adenocarcinoma | predicted - sensitive | Sapitinib | Preclinical - Patient cell culture | Actionable | In a preclinical study, Sapitinib (AZD8931) inhibited growth of tumor cells derived from the metachronous para-aortal lymph node metastasis harboring BRAF L597Q, which was resected from a patient with colon adenocarcinoma (PMID: 31704811). | 31704811 |
BRAF L597Q | colon adenocarcinoma | predicted - sensitive | Selumetinib | Preclinical - Patient cell culture | Actionable | In a preclinical study, Koselugo (selumetinib) inhibited growth of tumor cells derived from the metachronous para-aortal lymph node metastasis harboring BRAF L597Q, which was resected from a patient with colon adenocarcinoma (PMID: 31704811). | 31704811 |
BRAF L597Q | lung cancer | sensitive | Ulixertinib | Case Reports/Case Series | Actionable | In a Phase I trial, treatment with Ulixertinib (BVD-523) resulted in a partial response in a lung cancer patient harboring BRAF L597Q (PMID: 29247021; NCT01781429). | 29247021 |
