Do deaf father/mother produce deaf babies?

Does the deaf “gene” get passed down to offspring? What are the risks of having deaf/heard-of-hearing kids if one of the parents is deaf/hoh?

Thanks.

I can’t answer anything about generalities, because I have known only one person whose parents were deaf (both of them). He wasn’t. He was one of the kids in the neighborhood where I was living. I didn’t know about his deaf parents until I was invited to his house and couldn’t talk with them directly. He had to be the translator.

One is obviously not enough of a sample to generalize from, but it might offer some information. I hope that helps.

It runs in families. Google Connexin 26. It’s a very heavy and complicated subject. The DNA work on this is just getting started.

If both parents carry a particular recessive gene they have a 25% chance of having a totally deaf baby. They can pass on the mutation to a child who has no symptoms but carries the defect and can pass it on to their children.

Funny, but some how the human race seemed to have had a 6th sense about this mutation before this cause was discovered and that may explain why deaf people are treated differently. About 1 out of 500-1000 babies are born with this defect.

Some inbred groups seem to be particularly prone.

On Chromosome 13 Connexin 30 can also cause deafness. On 26 their are over 90 some variations that can cause deafness. Very complex but a good candidate for stem cell research…

We have a Grandchild who has this condition. A Cochlear implant at 8 months in both ears seems to be working. At 18 months seems ok but at that age there are sorts of variations in development in speech.

An operation like this and follow up can run about $200,000. She is learning sign language as a back up. No one knows what will happen 50 years from now.

If it’s a genetic problem then there’s always the possibility that the gene can be passed on. but it doesn’t mean it’s definitely going to happem.

It is best to talk to an specialists… There are genetic test to determine if it
could be pass on.

It is not necessary that child is also deaf if their parents are. But in most of cases it is found that deafness is genetic. A gene has been discovered which is the prime cause of deafness in new born and people can cure that gene.

Not all the times. It only happens some times and totally depends on genes and the chances may vary from person to person. This may enhance if both the parents are deaf. But does not happen in all the cases.

This absolutely depends on the cause of the hearing loss. My daughter’s hearing loss is a result of a virus I caught during pregnancy. It is probably responsible for a good percentage of the hearing loss out there. For people born in the 70s and earlier, a major cause was rubella. Then there are things that happen after birth, like ototoxic drugs, meningitis, etc.

So if only one parent’s hearing loss was genetic and the other’s wasn’t, chances are the baby will not inherit it.

I think something like 90% of deaf babies are born to hearing parents.

Just like any genetically disorder, the answer is yes, if the parents is deaf, genetically, then there would be a chance that the newborn child might be deaf as well. But, to the bright side, there are still possibilities that the child might end up being normal, and there would be no problems to his hearing as well. Most of the doctors would advise patients as well and to go through the family history to check out the possibilities.

This reminds me of the TV series I saw during the year. Boring had high hopes that the baby is deaf. The program continued throughout pregnancy, childbirth and evidence baby.I not believe what I saw, when the parents are happy that their son was born deaf. His thesis is that they want their children to live their lives as they had done. It was very bad. Why would anyone celebrate the childs disability?

All i know about this subject is that I know a man with good hearing and both of his parents were deaf

I’m most likely one of those born with this defect. I was born of two parents with Ashkenazim Jewish lineage and the chance of any Ashkenazim carrying the defect of either Connexin 26 or 30 is 1 in 25, wiki link. I saw an ENT and had an MRI done as well as numerous audiograms, tympanograms, nasal scope, and even had my tonsils and adenoids removed to relieve pressure on my Eustachian tubes. All of this showed no medical reason to my hearing loss - it was pretty much decided then that it was a genetic disorder.

I had no clue that this gene could be tested for. I’m going to make an appointment with my GP to get blood drawn to check for a GJB2/GJB6 defect. I’ve hit my deductible for the year so I might as well take advantage of it.

I just wanted to let you know that my dad was hearing impaired and it passed onto my older brother and I. I have a daughter who is 3 and is also hearing impaired. We are actually in the process of visiting a genetic councilor who can help us understand this process and to see if my daughter and my brother will pass this along to their kids.
