BRAF V600E staining in malignant melanoma.
The BRAF V600E mutation is a common recurrent mutation in the BRAF gene that is seen in many types of cancer.
BRAF gene, formally known as v-RAF murine sarcoma viral oncogene homolog B1, is a serine threonine kinase.[1]
The mutation can be demonstrated with molecular testing. Also, a mutation specific immunostain (VP1) is available.[2]
Positive
Commonly mutated
- Malignant melanoma (55%).[3]
- Papillary thyroid carcinoma (79%).[4]
- Ganglioglioma (58%).[5]
- Pleomorphic xanthoastrocytoma (78%).[6]
Less commonly mutated
- Colorectal cancer (5.5%).[3]
- Ovarian cancer (7%).[3]
- Lung adenocarcinoma (5%).[7]
