Neurofibromatosis (NF) is a genetic disorder that causes tumors to grow on nerves. There are two types, NF1 and NF2, with NF2 generally more severe as it affects the central nervous system. NF is caused by changes in the NF1 or NF2 genes and has autosomal dominant inheritance. Symptoms vary but can include skin spots, nerve tumors, pain, and learning disabilities. While there is no cure, treatments include surgery to remove tumors and chemotherapy if tumors become cancerous. NF affects people differently and can impact daily life through physical problems, pain, or learning disabilities.
