NF1 and blue nevus: To determine whether NF1 loss plays a role in GNAQ-driven melanoma, such as forms in the dermis or eye, we surveyed the published literature and The Cancer Genome Atlas (TCGA) uveal melanoma dataset (UVM) to see whether there were copy-number changes in NF1 reported in intradermal melanocytic lesions (“blue nevus” types) or uveal melanoma.
