Hereditary Hearing Loss
Most of the time, our focus is on hearing loss that is noise-induced or caused by ageing or other environmental factors. However, hearing loss and deafness can be passed down genetically, which is what hereditary hearing loss is. It is also called genetic hearing loss or congenital hearing loss. Certain genetic factors can put people at a great risk for hearing loss than others. This means that genetic mutations might cause hearing loss or they are more susceptible to hearing loss from ageing or loud noise.
Instances of Hereditary Hearing Loss
Wikipedia details how common hereditary hearing loss is.
- About 75 – 80% of inherited hearing loss is in recessive genes. This is called non-syndromic hearing impairment.
- 20 – 25% of inherited hearing loss is from dominant genes. This is called syndromic hearing impairment. It means that the hearing loss is attributed to other clinical abnormalities.
- Only 1 -2% of inherited hearing loss is inherited by X-linked patterns.
- Less than 1% is from a mitochondrial inheritance.
Examples of Hereditary Hearing Loss
Hereditary hearing loss can be a side effect of certain conditions including:
- Usher’s Syndrome
- Pendred Syndrome
Hereditary hearing loss can also be caused by a genetic mutation. This can affect the hair cells of the inner ear that are responsible for hearing. Even though one might be born with this type of gene mutation, hearing loss may not appear until later in life. Scientists are actively working on gene mapping to help with diagnosis, research, treatment and a cure.
