Mutations to the neurofibromin protein are implicated in the progression of Neurofibromatosis type 1 (NF1). This condition drives several forms of human cancers by inactivating the Ras suppression effects of NF, allowing Ras to behave as an oncogene. Neurofibromatosis type 1 is an autosomal dominant disorder that affects 1 in 3,000 people, and the NF gene itself has the highest mutation rate of any known human gene, adding to its prevalence[1]. NF1 primarily causes tumors in the central and peripheral nervous systems, but often has a multisystem expression including tumors in the dermatologic, cardiovascular, gastrointestinal, and orthopedic systems[2]. The wide range of presentations is consistent with the multiplicity of mutations observed in the causative protein[3].
