BRAF mutations in conjunctival melanoma.

Purpose: An activating mutation in exon 15 of the BRAF gene has been found in a high proportion of cutaneous melanomas and cutaneous nevi but not in uveal melanoma. Conjunctival melanoma shows greater clinical similarity to cutaneous melanoma than does uveal melanoma. The purpose of this study was to determine whether the T1799A BRAF mutation found in cutaneous melanoma is also present in conjunctival melanoma.
