USH1C

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

What is the official name of the USH1C gene?

The official name of this gene is “Usher syndrome 1C.”

USH1C is the gene's official symbol. The USH1C gene is also known by other names, listed below.

What is the normal function of the USH1C gene?

From NCBI Gene (http://www.ncbi.nlm.nih.gov/gene/10083):

This gene encodes a scaffold protein that functions in the assembly of Usher protein complexes. The protein contains PDZ domains, a coiled-coil region with a bipartite nuclear localization signal and a PEST degradation sequence. Defects in this gene are the cause of Usher syndrome type 1C and non-syndromic sensorineural deafness autosomal recessive type 18. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

From UniProt (USH1C_HUMAN) (http://www.uniprot.org/uniprot/Q9Y6N9):

Required for normal development and maintenance of cochlear hair cell bundles. Anchoring/scaffolding protein that is a part of the functional network formed by USH1C, USH1G, CDH23 and MYO7A that mediates mechanotransduction in cochlear hair cells. Required for normal hearing.

How are changes in the USH1C gene related to health conditions?

Genetics Home Reference provides information about these conditions associated with changes in the USH1C gene:
  • nonsyndromic hearing loss
  • Usher syndrome
UniProt (USH1C_HUMAN) (http://www.uniprot.org/uniprot/Q9Y6N9) provides the following information about the USH1C gene's known or predicted involvement in human disease.

Usher syndrome 1C (USH1C): 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.

Deafness, autosomal recessive, 18A (DFNB18A): 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 Gene (http://www.ncbi.nlm.nih.gov/gene/10083) lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the USH1C gene.
  • Deafness, autosomal recessive 18
  • Usher syndrome, type 1
  • Usher syndrome, type 1C
