Mutational profile of GNAQQ209 in human tumors.

<h4>Background</h4>Frequent somatic mutations have recently been identified in the ras-like domain of the heterotrimeric G protein alpha-subunit (GNAQ) in blue naevi 83%, malignant blue naevi (50%) and ocular melanoma of the uvea (46%). The mutations exclusively affect codon 209 and resu...
