The information on this page was automatically extracted from online scientific databases.

What is the official name of the PCDH15 gene?

The official name of this gene is “protocadherin-related 15.”

PCDH15 is the gene's official symbol. The PCDH15 gene is also known by other names, listed below.

What is the normal function of the PCDH15 gene?

From NCBI GeneThis link leads to a site outside Genetics Home Reference.:

This gene is a member of the cadherin superfamily. Family members encode integral membrane proteins that mediate calcium-dependent cell-cell adhesion. It plays an essential role in maintenance of normal retinal and cochlear function. Mutations in this gene result in hearing loss and Usher Syndrome Type IF (USH1F). Extensive alternative splicing resulting in multiple isoforms has been observed in the mouse ortholog. Similar alternatively spliced transcripts are inferred to occur in human, and additional variants are likely to occur. [provided by RefSeq, Dec 2008]

From UniProt (PCD15_HUMAN)This link leads to a site outside Genetics Home Reference.:

Calcium-dependent cell-adhesion protein. Essential for maintenance of normal retinal and cochlear function.

How are changes in the PCDH15 gene related to health conditions?

Genetics Home Reference provides information about these conditions associated with changes in the PCDH15 gene:
UniProt (PCD15_HUMAN)This link leads to a site outside Genetics Home Reference. provides the following information about the PCDH15 gene's known or predicted involvement in human disease.

Usher syndrome 1F (USH1F): USH is a genetically heterogeneous condition characterized by the association of retinitis pigmentosa with sensorineural deafness. Age at onset and differences in auditory and vestibular function distinguish Usher syndrome type 1 (USH1), Usher syndrome type 2 (USH2) and Usher syndrome type 3 (USH3). USH1 is characterized by profound congenital sensorineural deafness, absent vestibular function and prepubertal onset of progressive retinitis pigmentosa leading to blindness. The disease is caused by mutations affecting the gene represented in this entry.

Usher syndrome 1D/F (USH1DF): USH1DF patients are heterozygous for mutations in CDH23 and PCDH15, indicating a digenic inheritance pattern. The disease is caused by mutations affecting distinct genetic loci, including the gene represented in this entry.

Deafness, autosomal recessive, 23 (DFNB23): 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.

NCBI GeneThis link leads to a site outside Genetics Home Reference. lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the PCDH15 gene.
  • Deafness, autosomal recessive 23
  • Usher syndrome, type 1D
  • Usher syndrome, type 1F
