Summaries for COCH Gene

Entrez Gene Summary for COCH Gene

  • The protein encoded by this gene is highly conserved in human, mouse, and chicken, showing 94% and 79% amino acid identity of human to mouse and chicken sequences, respectively. Hybridization to this gene was detected in spindle-shaped cells located along nerve fibers between the auditory ganglion and sensory epithelium. These cells accompany neurites at the habenula perforata, the opening through which neurites extend to innervate hair cells. This and the pattern of expression of this gene in chicken inner ear paralleled the histologic findings of acidophilic deposits, consistent with mucopolysaccharide ground substance, in temporal bones from DFNA9 (autosomal dominant nonsyndromic sensorineural deafness 9) patients. Mutations that cause DFNA9 have been reported in this gene. Alternative splicing results in multiple transcript variants encoding the same protein. Additional splice variants encoding distinct isoforms have been described but their biological validities have not been demonstrated. [provided by RefSeq, Oct 2008]

  • Deafness, autosomal dominant, 9 (DFNA9) [MIM:601369]: A form of non-syndromic hearing loss characterized by onset in the fourth or fifth decade of life and initially involves the high frequencies. Hearing loss is progressive and usually complete by the sixth decade. In addition to cochlear involvement, DFNA9 patients also exhibit a spectrum of vestibular dysfunctions. Penetrance of the vestibular symptoms is often incomplete, and some patients are minimally affected, whereas others suffer from severe balance disturbances and episodes of vertigo. Affected individuals have mucopolysaccharide depositions in the channels of the cochlear and vestibular nerves. These depositions apparently cause strangulation and degeneration of dendritic fibers. {ECO:0000269 PubMed:10400989, ECO:0000269 PubMed:11295836, ECO:0000269 PubMed:12928864, ECO:0000269 PubMed:14512963, ECO:0000269 PubMed:16835921, ECO:0000269 PubMed:17561763, ECO:0000269 PubMed:18312449, ECO:0000269 PubMed:22610276, ECO:0000269 PubMed:22931125, ECO:0000269 PubMed:23993205, ECO:0000269 PubMed:25388789, ECO:0000269 PubMed:9806553, ECO:0000269 PubMed:9931344}.
