We further classified the 89 samples into the four molecular subtypes, BRAF mutated (47% in melanoma TCGA), RAS mutated (NRAS/KRAS/HRAS mutations, 29%), NF1 mutated (9%), and Triple-WT (subgroup lacking above mutations, 15%), proposed by the recent TCGA melanoma cohort [5]. Here, KRAS is linked to melanoma.
