SLC26A8
SLC26A8 Gene: Unraveling Its Role in Health and Disease
Description
The SLC26A8 gene, also known as prestin, is a vital component responsible for the remarkable hearing ability of mammals. It encodes a motor protein that drives the electromotility of outer hair cells (OHCs), specialized sensory cells in the inner ear. These OHCs play a crucial role in amplifying and tuning sound waves, enabling us to perceive a wide range of frequencies and sounds.
Associated Diseases
Mutations in the SLC26A8 gene have been linked to several hearing disorders, including:
- Nonsyndromic hearing loss (NSHL): The most common type of hearing loss associated with SLC26A8 mutations, affecting both children and adults.
- Usher syndrome type 1F (USH1F): A rare inherited condition characterized by deafness, vision loss (retinitis pigmentosa), and vestibular dysfunction.
- Pendred syndrome: A disorder involving sensorineural hearing loss and enlargement of the thyroid gland (goiter).
Did you Know ?
Studies have shown that SLC26A8 mutations are responsible for approximately 5-10% of cases of nonsyndromic hearing loss worldwide.
