What are the chances of a person with this disease passing the disease to their offspring?

If a person is diagnosed with hereditary deafness, then there is a good chance their child will be as well, but you can't always predict if a child will have this.

A child is born with two parents who can hear very well, but the child is born deaf. The parents had no clue this would happen and wonder how it did.

A newborn can be born as deaf or hard-of-hearing, even if the hereditary deafness is far back into the each of the parent's family history or not prevalent at all.
