Panelists discuss how neurofibromatosis type 1 (NF1) is typically diagnosed in early childhood using National Institutes of Health (NIH) clinical criteria, with genetic testing supporting unclear cases, and highlight the global prevalence of NF1 and the high incidence of plexiform neurofibromas, which affect up to 50% of patients regardless of racial or geographic background.

Panelists discuss how mutations in the NF1 gene lead to loss of neurofibromin function, resulting in hyperactivation of the RAS/MAPK and PI3K/AKT/mTOR pathways, and how this molecular dysregulation drives abnormal cell proliferation and tumor development in NF1.
