We are proud to announce that PhenoPath is now a Quest Diagnostics Company.
The FDA-approved cobas 4800 BRAF V600 mutation test (IVD) is a real-time PCR assay designed to detect the presence of activating BRAF V600 mutations in melanoma and is the companion diagnostic test for the vemurafenib, a BRAF inhibitor. This assay will detect the V600E BRAF mutation (T1799A) as well as a subset of other less common activating BRAF V600 mutations (including some V600K BRAF mutations). BRAF mutations have been identified in 40% - 60% of malignant melanomas as well as other human cancers including colorectal cancer, ovarian cancer, and thyroid cancer. BRAF is part of a highly regulated signaling pathway that mediates the effects of growth factor receptors (such as EGFR) through RAS, RAF, MEK and ERK. Oncogenic mutations in BRAF result in a gain of kinase function, rendering the RAF-MEK-ERK pathway constitutively active in the absence of typical growth factors.
