What is the official name of the DFNA5 gene?

The official name of this gene is “deafness, autosomal dominant 5.”

DFNA5 is the gene's official symbol. The DFNA5 gene is also known by other names, listed below.

What is the normal function of the DFNA5 gene?

From NCBI Gene (

Hearing impairment is a heterogeneous condition with over 40 loci described. The protein encoded by this gene is expressed in fetal cochlea, however, its function is not known. Nonsyndromic hearing impairment is associated with a mutation in this gene. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

From UniProt (DFNA5_HUMAN) (

Involved in apoptosis and cell survival. Plays a role in the TP53-regulated cellular response to DNA damage probably by cooperating with TP53.

How are changes in the DFNA5 gene related to health conditions?

Genetics Home Reference provides information about nonsyndromic hearing loss, which is associated with changes in the DFNA5 gene.
UniProt (DFNA5_HUMAN) ( provides the following information about the DFNA5 gene's known or predicted involvement in human disease.

Deafness, autosomal dominant, 5 (DFNA5): A form of non-syndromic sensorineural hearing loss. Sensorineural deafness results from damage to the neural receptors of the inner ear, the nerve pathways to the brain, or the area of the brain that receives sound information. The disease is caused by mutations affecting the gene represented in this entry.

Is a tumor suppressor gene with an important role in colorectal cancer (CRC).

NCBI Gene ( lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the DFNA5 gene.
  • Deafness, autosomal dominant 5 (, a catalog designed for genetics professionals and researchers, provides the following information about the DFNA5 gene and its association with health conditions.

Where is the DFNA5 gene located?
