Spitzoid Melanoma, also known as atypical spitz nevus, is related to spitz nevus and melanocytic nevus syndrome, congenital. An important gene associated with Spitzoid Melanoma is ROS1 (ROS Proto-Oncogene 1, Receptor Tyrosine Kinase), and among its related pathways/superpathways are Apoptotic Pathways in Synovial Fibroblasts and ERK Signaling. Affiliated tissues include skin and lymph node, and related phenotypes are Decreased viability and Increased shRNA abundance (Z-score > 2)
