Negative NF2 test often confirm 'mosaic NF2'. It is a milder form of NF2.
Ive been diagnosed (6 months ago) with mosaic NF2. I have a 10mm x 6mm x 6mm left side VS with moderate hearing loss and tinnitus. I also have a 15mm x 5mm hypoglossal tumor with no symptoms. I addition i have 3 tiny spinal nodules...about 6mm each.
Odd thing is i also have hearing loss and tinnitus on the right although no VS on that side..the theory (and doctors agree) is that I must have some noise induced hearing loss from being a producer in front of loud music for the past 15 years!If anything, this noise induced hearing loss mustve made me notice the 'overall' hearing loss on my left side earlier than if it had been just the hearing loss from the VS..
I too had a negative genetic testing for NF2 which confirmed my doctor's diagnosis of mosaic NF2.
So I guess you can add me to the NF2 list
