BRAF and NRAS are common targets for somatic mutations in benign and malignant neoplasms that arise from melanocytes situated in epithelial structures and lead to constitutive activation of the MAP-kinase pathway. However, BRAF and NRAS mutations are absent in a number of other melanocytic neoplasms in which the equivalent oncogenic events are currently unknown. We report frequent somatic mutations in the heterotrimeric G protein alpha subunit, GNAQ, in blue nevi (83%) and ocular melanoma of the uvea (46%). The mutations occur exclusively in codon 209 in the ras-like domain and result in constitutive activation, turning GNAQ into a dominant acting oncogene. Our results demonstrate an alternative route to MAP-kinase activation in melanocytic neoplasia providing new opportunities for therapeutic intervention.
