To determine the frequency of these mutations, we searched the COSMIC database to identify all cutaneous melanoma cases with a GNAQ or GNA11 oncogenic mutation at either Q209 or R183; 2753 and 2295 samples meeting our inclusion criteria (see legend of Supplementary file 2b and c) had GNAQ or GNA11 mutation status reported, respectively. This evidence concerns the gene GNA11 and cutaneous melanoma.
