What is the normal function of the DFNB59 gene?
The DFNB59 gene provides instructions for making a protein called pejvakin. This protein is present in the nerves leading from the inner ear to the brain (auditory nerves). It is also found in the part of the brain that is connected to the spinal cord (the brainstem). Although the exact function of pejvakin is uncertain, it appears to be essential for normal hearing. Hearing requires the conversion of sound waves to nerve impulses that are transmitted via the auditory nerves to the brain. Researchers believe that pejvakin may play a role in the transmission of nerve impulses that register sound.
