Use

This test is intended for individuals who have clinical or suspected diagnoses of schwannomatosis or NF2-related schwannomatosis. It is also suitable for individuals displaying features such as bilateral vestibular schwannomas accompanied by tinnitus, hearing loss, and balance dysfunction. Additionally, it is for individuals presenting NF2-like characteristics without bilateral vestibular schwannomas, as well as children with retinal hamartoma, optic nerve thickening, cortical wedge cataracts, or unexplained third cranial nerve palsy. It targets individuals who experience symptom onset from the second to fourth decades of life.
