Common symptoms and their severity as reported by people on Patientslikeme.

• Neurofibromatosis is caused by genetic mutations that are either inherited or are acquired spontaneously.
• The disease follows an autosomal dominant pattern of inheritance which means that a child can be affected even if one defective gene is inherited.
• Mutations (defects) in NF1 gene result in abnormal/no neurofibromin protein which causes NF1. defects in NF2 gene cause abnormality in/loss of protein called merlin leading to NF2 disease. Both these proteins have a role in cell growth regulation.
• The risk factors include:
• Family history

There are no preventive measures.
