Neurofibromatosis Type 1 (NF1) Overview

Neurofibromatosis type 1 (NF1) is a complex, autosomal dominant neurocutaneous syndrome caused by loss-of-function mutations in the NF1 tumor suppressor gene, which leads to a profound deficiency of neurofibromin and subsequent unchecked hyperactivation of the RAS/MAPK signaling pathway. Clinically, the disorder is characterized by nearly complete penetrance but highly variable expressivity, classically manifesting with pigmentary anomalies—including multiple café-au-lait macules and intertriginous freckling—alongside Lisch nodules of the iris, optic pathway gliomas, and distinctive osseous dysplasias. The phenotypic hallmark of NF1 is the development of peripheral nerve sheath tumors; while cutaneous neurofibromas emerge predominantly in adulthood and remain strictly benign, congenital plexiform neurofibromas (PNs) grow expansively along deep nerve branches, causing severe pain, anatomical disfigurement, and functional compromise, while carrying a significant lifetime risk of malignant transformation into highly aggressive Malignant Peripheral Nerve Sheath Tumors (MPNST). Historically, management of PNs was entirely restricted to challenging surgical resections with high recurrence rates; however, the modern therapeutic paradigm has been completely revolutionized by the advent of targeted RAS/MAPK pathway modulation. The standard of care for symptomatic, inoperable plexiform neurofibromas now heavily relies on oral MEK inhibitors (such as selumetinib), which have demonstrated unprecedented efficacy in shrinking tumor volume and significantly improving long-term clinical outcomes.
