4. Spontaneous mutation
It’s worth noting that not all cases of NF2 are hereditary. About half of all patients who have NF2 and schwannomas developed the condition as a result of a genetic mutation. This occurs in the time of conception This means that you could develop NF2 and schwannomas even if your family doesn’t have a history of the condition.
If you notice schwannomas developing on your body then you should still have yourself tested for NF2 despite having no family history of the disease as you may have developed it due to a spontaneous mutation. It’s worth noting that there’s no difference in the severity of the disease nor the symptoms when you develop it due to a spontaneous mutation rather than hereditarily. If your schwannomas are, in fact, being caused by a spontaneous mutation case of NF2 then doctors will be able to diagnose it using genetic testing.
