Schwannomatosis

Common Name(s)

Schwannomatosis

Schwannomatosis is a rare form of neurofibromatosis that is genetically and clinically distinct from NF1 and NF2.  Inherited forms of the disorder account for only 15 percent of all cases.  Researchers have identified a mutation of the SMARCB1/INI1 gene that is associated with the familial form of the disease but donĂ•t fully understand what causes the intense pain that characterizes this disorder. In addition to severe chronic pain, other neurological symptoms such as numbness, tingling, or weakness in the fingers and toes may occur. The pain associated with schwannomatosis may be managed with surgery and medication.
