Can people with NF2 have children?
About 1 in 3 people with NF2 have a form of the disease called mosaic NF2. The symptoms of mosaic NF2 are milder and often restricted to a certain area or side of the body. People with mosaic NF2 have lower than the usual 50% risk of having a child with NF2.
Is there a cure for NF2?
While there is currently no cure for NF2, there are clinical trials available at the Johns Hopkins Comprehensive Neurofibromatosis (NF) Center.
Do all NF2 patients go deaf?
Most patients with neurofibromatosis type II (NF-II) will eventually encounter bilateral deafness, creating an obstacle to social life.
