    The report provides a summary of the discussions that have taken place within the framework of Forum activities on how the strategies, structures and practices of governments must change in the coming years, and how new networks and technologies can be leveraged to transform government capacity. It includes a series of policy briefs, which distils some of the most current and vital information for government modernization available, and concludes with case studies from around the world

    Frequent somatic mutations of GNAQ in uveal melanoma and blue naevi

    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 mitogen-activated protein (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. Here we report frequent somatic mutations in the heterotrimeric G protein alpha-subunit, GNAQ, in blue naevi (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
