Autosomal Hearing Loss

The parent who carries the dominant gene for hearing loss passes it on to their child and due to this autosomal dominant hearing loss is occur. Under this condition at least a 50-percent possibility that the child will also be afflicted with some form of hearing loss. The possibilities of the children being pretentious by a hearing loss are higher if both parents bring the dominant gene and both suffer from a hearing loss. The same is true if both of the grandparents on one side of the family have a hearing loss because of inherited reasons. Because no less than one parent has a hearing loss and due to this it is frequently predictable that their children may also have a hearing loss.

Always remember that with autosomal recessive hearing loss both of the parents who generally have normal hearing carry a recessive gene. In this occasion the possibility that a child will undergo some form of hearing loss is only near about 25-percent. According to medical science if both parents have normal hearing and if no other family members suffer from hearing loss then there is no anticipation that their child will have a hearing loss.

Always remember that if a parent carries a recessive hearing loss gene then it can frequently pass through many age groups and never cause a hearing loss in anybody. Autosomal hearing loss is only take place in a child when a mother with a recessive gene has a baby with a father who carries a recessive gene. The most common forms of autosomal recessive hearing loss is occurs after the alternation of the gene. An autosomal recessive hearing loss is take place in a gene called connexin 26. According to medical professionals any child who receives two altered connexin 26 genes will possibly be born with a hearing loss. A lot of heredity clinics will test for the connexin 26 gene alteration but there are also many other recessive genes due to which hearing loss is take place. According to medical science there are no tests for most of these genes. Hence, if your child does not have the connexin 26 gene alternation then it can be hard to find out what is causing their hearing loss.
