Basal Cell Nevus Syndrome 1, also known as basal cell nevus syndrome, is related to basal cell carcinoma 1 and basal cell nevus syndrome 2. An important gene associated with Basal Cell Nevus Syndrome 1 is PTCH1 (Patched 1), and among its related pathways/superpathways are Regulation of activated PAK-2p34 by proteasome mediated degradation and ERK Signaling. The drugs Verteporfin and Veratrum Alkaloids have been mentioned in the context of this disorder. Affiliated tissues include skin and heart, and related phenotypes are cerebral calcification and melanocytic nevus
