Deafness is an etiologically heterogeneous trait with many known genetic and environmental causes. Genetic factors account for at least half of all cases of profound congenital deafness, and can be classified by the mode of inheritance and the presence or absence of characteristic clinical features that may permit the diagnosis of a specific form of syndromic deafness. The identification of more than 120 independent genes for deafness has provided profound new insights into the pathophysiology of hearing, as well as many unexpected surprises. Although a large number of genes can clearly cause deafness, recessive mutations at a single locus, GJB2 or Connexin 26, account for more than half of all genetic cases in some, but not all populations.

What form of deafness is caused by disease to the three tiny bones of the inner ear?
conduction deafness
What happens as you get older when the small ear bones get joined together?
This is called auditory ossical fusion or fixation and it causes conductive deafness. It is usually treated by installing a hearing aide.
What causes the most genetic diversity in a bacterial colony?
The most common source of genetic diversity in a bacterial colony is a mutation. External DNA is assimilated by a cell is transformation.
Is deafness hereditary?
Like allergies and birthmarks, deafness as a symptom by itself is not genetic. Deafness as a symptom of a disease which is genetic, is genetic.

What are the causes of partial deafness?
what are the cause of partial deafness
What sort of genetic defects does a Dalmatian has?
deafness
Are there any links between mmr and genetic deafness?
Not at all. By MMR, I don't know if you're refering to the set of diseases (measles, mumps and rubella) or the MMR vaccine designed to immunize a person against such diseases. Either way, genetic deafness is caused by genetic factors as the name suggests. A vaccine or a virus is not going to alter your DNA to cause deafness.
What genetic fault do some dalmatians have?
Some dalmatians develop deafness as a problem.

What is bone deafness?

Damage to this cerebral lobe causes cortical deafness?
Temporal lobe
What is the type of mutation that causes deafness?
that would be a hereditary thing not a gene mutaion
What are the causes of genetic human disorders?
The causes of genetic disorders areThey can be inherited through Parents;Mutations may occur;A deletion may occur.These are the causes of a genetic disorder.
What is it called when you can't hear?
Complete lack of hearing is called deafness. Various causes of deafness are defined by specific medical conditions (e.g. presbycusis - old age hearing loss). The term for less than complete deafness is "hearing impairment".
