In a study performed on 100 primary melanomas matched with 25 metastatic tumors aimed to identify the best combination of methods for detecting BRAF mutations (among PNA-clamping real-time PCR, IHC, and Sanger sequencing), a BRAF mutation frequency of 62%, based on the combination of at least two techniques was obtained (Bruno et al., 2017). Here, BRAF is linked to melanoma.
