The ForeSENTIA BRAF Gene-Focused Panel tests for single nucleotide variants, insertions and deletions on the BRAF gene. BRAF is a gene found in chromosome 7 and it is transcribed into a serine/threonine protein kinase also known as BRAF. This protein is essential in cell growth, regulation of cell signaling pathways, and cell division.
In cancer, the BRAF gene is frequently mutated resulting in abnormal regulation of the cell signaling pathways and ultimately uncontrolled growth of the cancer cells. Examples of cancers in which BRAF is found to be mutated are melanoma, NSCLC, colorectal, ovarian, glioma, and others. Different mutations of the BRAF gene have been observed in cancer patients. One of the most common is the V600E mutation and it is frequently found in melanoma, colorectal, thyroid, and other types of cancer.
There are several drugs that are currently used for certain tumors and target BRAF mutations. Some examples include vemurafenib, dabrafenib, and encorafenib.
Recommendations by professional bodies:
ESMO recommends BRAF genetic testing in high-risk resected melanoma (stage IIC) and it is mandatory for advanced melanoma
NCCN recommends BRAF testing in advanced melanoma patients for targeted therapy options
