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