Hereditary Hearing Loss Explained
We often talk about how hearing loss is caused by ageing or is noise-induced. However, hearing loss can also be hereditary, meaning that it is passed down in the genes. Certain genetic factors can make people more susceptible to hearing loss than others. Besides being more susceptible to hearing loss due to ageing or loud noise, there are other conditions that might be passed on through the genes or there can also be a genetic mutation present. Hereditary hearing loss is also called genetic hearing loss or congenital hearing loss.
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 present itself in certain conditions including:
- Usher’s Syndrome
- Pendred Syndrome
Hereditary hearing loss can also be present in the form of genetic mutations. These mutations can affect the inner ear of the hair cells of the inner ear that are responsible for hearing. Even though one might be born with this time of gene mutation, it may not present itself at birth, sometimes they appear later in life. Scientists are actively working on gene mapping to help in this area in order to detect the problem early on as well as looking for cures or treatment options.
