Hereditary deafness can be caused by both recessive and dominant genetic mutations. Autosomal recessive inheritance typically requires two copies of the mutated gene for deafness to manifest, while autosomal dominant inheritance only requires one copy of the mutated gene. There are also other forms of inheritance, such as X-linked and mitochondrial inheritance, that can cause hereditary deafness.
loss or or total lack of hearing abilities
It depends on whether the cause of the deafness is hereditary or environmental. If it's hereditary then probably.
that would be a hereditary thing not a gene mutaion
their only limitation is not being able to hear.
This condition would have no impact on life expectancy.
Deafness can be hereditary or be "contracted" by listening to loud music. Working in a loud environment for an extended period of time without the proper protection can cause hearing loss.
Tone deafness seems to be mostly hereditary and is more of a difficulty distinguishing between pitches inside the brain than a deafness that causes you to not be able to hear.
CODA stands for Child Of Deaf Adult. They might be able to hear or not. It depends if the parent's deafness is hereditary.
Hereditary deafness is inherited by a person's parent, or parents, based on their genes. In the chromosomes, just as a person's hair or eye color is identified, a person's hearing balance can be passed on, dominant or recessive, syndromic or nonsyndromic. Syndromic being associated with certain hearing traits as well as hearing impairment. Nonsyndromic being hearing loss as its only impairment.Dominant transmission of deafness needs only one faulty gene, from either parent to cause the hearing loss, however recessive transmission of deafness requires a faulty gene from both the mother and father.
Diseases such as Diabetes mellitus and deafness (DAD), Leber's hereditary optic neuropathy (LHON), Leigh syndrome, and Myoneurogenic gastrointestinal encephalopathy (MNGIE) can be considered to be mitochondrial disorders.
