Frequent somatic mutations of GNAQ in uveal melanoma and blue naevi

Dec 2008

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 pathwayHowever, 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 α-subunit, GNAQ, in blue naevi (83%) and ocular melanoma of the uvea (46%).

Gene expression profiling in uveal melanoma reveals two molecular classes and predicts metastatic death

Oct 2004

Melanomas are notoriously difficult to classify because of a lack of discrete clinical and pathological stages. Here, we show that primary uveal melanomas surprisingly cluster into two distinct molecular classes based on gene expression profile.
