Clinical trials of similar drugs are currently ongoing for children and adults. 7th ed. They are common in people with NF1, and an ophthalmologist might spot them during an eye exam. Why tumors develop in these conditions isn’t completely known, but it appears to be caused in part by mutations in genes that play key roles in suppressing growth in nervous system cells. Other symptoms a doctor may look for are: There is no currently accepted medical treatment or drug for schwannomatosis. Treatments for other conditions associated with NF1 are aimed at controlling or relieving symptoms. Known growths are often imaged with periodic surveillance scans with treatment reserved for enlarging or symptomatic growths. Current basic and clinical research is aimed at understanding how the genetic mutations that cause NF1 tumors also cause neurons and neural networks to form abnormally during fetal development, which later result in the learning disabilities and cognitive deficits of children with the disorder. NF1 is caused by mutations in the gene that controls production of a protein called neurofibromin (neurofibromin 1). All rights reserved.
