Overview

NCI Definition: A melanoma derived from melanocytes of the uveal tract. It is the most common primary intraocular tumor in the United States and Western Europe. Similar to melanoma of the skin, it is rare in Africa and Asia. Diagnostic procedures include ophthalmoscopic exam, fluorescein angiography and ultrasound. Treatment includes: surgical excision of the eye, iridocyclectomy and tumor resection. Recent treatments also include radiotherapy or photo coagulation. Classification of uveal melanomas recognizes four cell types within these tumors: epithelioid, intermediate, mixed cell, and spindle cell types. The spindle cell type uveal melanomas are further sub-classified as spindle cell type A and spindle cell type B. [1]

Uveal melanomas most frequently harbor alterations in GNA11, GNAQ, BAP1, SF3B1, and EIF1AX [2].

Most Commonly Altered Genes in Uveal Melanoma

GNA11 Mutation, GNA11 Exon 5 Mutation, GNA11 Codon 209 Missense, GNA11 Q209L, and GNAQ Mutation are the most common alterations in uveal melanoma [2].
