Hi K.,
NF1 is very rare but more common today than it used to be. Anytime I see something that affects the nerves/neurological system I dig a little deeper. This link seems to be one man's success story with NF1.

K., I do know that there are a lot of toxins in our homes, water, air, and our food supply and ultimately our bodies that have changed how our bodies function, i.e. mutations. (I do seminars and speak on environmental toxins and their relation to our health, specifically cancers and neurological problems like child behavioral disorders.) You may want to research a little deeper and see where this link takes you.
I'm terribly sorry you're dealing with this and I'm sorry I don't know more. If you need to talk feel free to email me back. I'll be praying!
God bless!
M.
