What is the official name of the DFNB59 gene?

The official name of this gene is “deafness, autosomal recessive 59.”

DFNB59 is the gene's official symbol. The DFNB59 gene is also known by other names, listed below.

What is the normal function of the DFNB59 gene?

From NCBI Gene (

The protein encoded by this gene is a member of the gasdermin family, a family which is found only in vertebrates. The encoded protein is required for the proper function of auditory pathway neurons. Defects in this gene are a cause of non-syndromic sensorineural deafness autosomal recessive type 59 (DFNB59). [provided by RefSeq, Dec 2008]

From UniProt (PJVK_HUMAN) (

Essential in the activity of auditory pathway neurons.

How are changes in the DFNB59 gene related to health conditions?

Genetics Home Reference provides information about nonsyndromic hearing loss, which is associated with changes in the DFNB59 gene.
UniProt (PJVK_HUMAN) ( provides the following information about the DFNB59 gene's known or predicted involvement in human disease.

Deafness, autosomal recessive, 59 (DFNB59): A form of sensorineural hearing impairment with absent or severely abnormal auditory brainstem response but normal otoacoustic emissions (auditory neuropathy or auditory dys-synchrony). Auditory neuropathies result from a lesion in the area including the inner hair cells, connections between the inner hair cells and the cochlear branch of the auditory nerve, the auditory nerve itself and auditory pathways of the brainstem. The disease is caused by mutations affecting the gene represented in this entry.

NCBI Gene ( lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the DFNB59 gene.
  • Deafness, autosomal recessive 59 (, a catalog designed for genetics professionals and researchers, provides the following information about the DFNB59 gene and its association with health conditions.

Where is the DFNB59 gene located?
