2. Description of conductive hearing loss
Symptoms and characteristics
Noggin is encoded by NOG and mutations in the gene are associated with aberrant skeletal formation, such as in the autosomal dominant disorders proximal symphalangism.
At first, investigated a Japanese pedigree with SYM1 and conductive hearing loss and found that it carried a novel heterozygous missense mutation of NOG.
If Noggin isn’t cured a lot of people wont be able to hear until it is cured.
Affinity of NOG with the p.R136C mutation to HSPG leads to an excess of BMP signaling and underlies the SYM1 and conductive hearing loss phenotype of carriers.

3. Description of conductive hearing loss (cont.)
Who is affected? Anyone, but the following have a higher risk:
It can happen to anyone no matter the age
Everyone over the age of 60, especially Americans
People with a family history of noggin
Outlook or quality of life
With early treatment, ears may be protected from serious hearing loss
Without treatment, individuals develop noggin and won’t be able to hear treatments such as laser procedure and/or surgery.
There is no cure for noggin; hearing that is lost cannot be restored.
