Is the connexin 26 gene (causes deafness) passed down from generations?

Recessive or dominan: This mutation can be passed down in either an autosomal dominant or more commonly autosomal recessive form. In the dominant form, if one parent is affected, there is a 50% -50% chance for every child to be healthy or have the mutation and therefore hearing loss. In the recessive form, a child would need to have 2 defective genes (one from each carrier parent) to have hearing loss.Hope this helps.
