Central Nervous System Melanocytic Neoplasm, also known as primary melanocytic lesion of meninges, is related to diffuse meningeal melanocytosis and meningeal melanomatosis. An important gene associated with Central Nervous System Melanocytic Neoplasm is GNAQ (G Protein Subunit Alpha Q), and among its related pathways/superpathways are Signal Transduction and ADORA2B mediated anti-inflammatory cytokines production. The drugs Temozolomide and Gamma Secretase Inhibitors and Modulators have been mentioned in the context of this disorder. Related phenotypes are nervous system and growth/size/body region
