BRAF gene mutation testing has emerged as an important tool for diagnosis, prognosis, treatment, and predicting patient outcome in response to targeted therapy.Evidence indicates BRAF gene mutation testing has a role in the following:he BRAF gene mutation test result is positive (ie, a mutation is present) if V600E is found in the BRAF gene. V600E is the most common gene mutation for the BRAF gene and is the most common mutation tested for in clinical laboratories.
