Conjunctival melanoma accounts for about 5–10% of all ocular melanomas, and displays a genomic landscape in terms of recurrently mutated genes (with BRAF and NRAS as the mostly frequently mutated gene) and copy number alterations similar to those observed in cutaneous melanomas, but entirely distinct from uveal melanomas (the other ocular melanomas) [150]. This evidence concerns the gene NRAS and cutaneous melanoma.
