Neurofibromatosis Type I, commonly referred to as NF1, is a genetic disorder that causes the growth of tumors along nerves in the body. Some synonyms for NF1 include von Recklinghausen's disease, peripheral neurofibromatosis, or simply neurofibromatosis. While rare, NF1 affects approximately one in every 2,500 to 3,000 individuals worldwide. Symptoms of the condition can vary widely, but may include skin pigmentation, learning difficulties, and skeletal abnormalities. It is important for individuals with NF1 to receive proper medical care and regular screenings to monitor for any potential complications or growth of tumors.
