Deafness question

I have a new character in one of my books who is deaf due to a completely non-functional auditory nerve as the result of a family curse.

Having read up on this kind of hearing loss on Wikipedia and several other websites, I now have a question. So it says in the research I've done that side effects are vertigo, dizziness, nausea, and balance issues. Problem is, given the context in the research, they're likely talking about the most statistically significant cause, which is gradual damage to the auditory nerve. I can't find anything that answers the following question:

If someone is born with an already non-functional auditory nerve, do they still have dizziness, vertigo, nausea, and balance issues?
