BRAF V600E positivity in malignant melanoma. VE1 immunostain.
The BRAF V600E mutation, also BRAF V600E, is a common recurrent mutation in the BRAF gene that is seen in many types of tumours and cancer.[1]
The BRAF gene, formally known as v-RAF murine sarcoma viral oncogene homolog B1, is a serine threonine kinase.[2]
The mutation can be demonstrated with molecular testing (ARMS). Also, a mutation specific immunostain (VE1) is available.[1]
Positive
Commonly mutated
- Malignant melanoma (55%).[3]
- Papillary thyroid carcinoma (79%).[4]
- Ganglioglioma (58%).[5]
- Pleomorphic xanthoastrocytoma (78%).[6]
- Hairy cell leukemia (>90%)
- Histiocytic disorders: Langerhans cell histiocytosis and Erdheim-Chester disease
Less commonly mutated
- Colorectal cancer (5.5%).[3]
- Ovarian cancer (7%).[3]
- Lung adenocarcinoma (5%).[7]
