The polyclonality of BRAF mutations in melanocytic nevi suggests that mutation of BRAF may not be an initial event in melanocyte transformation, according to a new brief communication published online September 14 in the Journal of the National Cancer Institute.

Molecular Nevogenesis

hindawi.com — “Despite recent advances, the biology underlying nevogenesis remains unclear. Activating mutations in NRAS, HRAS, BRAF, and GNAQ have been identified in benign nevi. Their presence roughly correlates with congenital, Spitz, acquired, and blue nevi, respectively. These mutations are likely to play a critical role in driving nevogenesis. While each mutation is able to activate the MAP kinase pathway, they also interact with a host of different proteins in other pathways. The different melanocytic dView full resource at hindawi.com
