Melanoma was one of the translational cancer examples in clinic, including target therapy related to specific biomarkers impacting in the outcome of melanoma patients. Melanomagenesis involved a wide variety of mutations during his evolution; many of these mutated proteins have a kinase activity. One of the most cited proteins in melanoma is BRAF (about 50-60 % of melanomas harbors activating BRAF mutations), for these the most common is a substitution of valine to glutamic acid at codon 600 (p.V600E). Therefore, the precise identification of this underlying somatic mutation is essential; knowing the translational implications has opened a wide view of melanoma biology and therapy.
