FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The protein encoded by this gene is specifically expressed in the inner ear, and is located at the interface between the apical surface of the inner ear sensory epithelia and their overlying acellular gels. It is prposed that this protein is involved in the attachment of the inner ear acellular gels to the apical surface of the underlying nonsensory cells. Mutations in this gene are associated with autosomal recessive deafness type 22 (DFNB22). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

PHENOTYPE: Mice homozygous for a knock-out allele exhibit hearing loss, detachment of the tectorial membrane from the spiral limbus, abnormal tectorial membrane morphology, absence of Hensen's stripe and increased cochlear nerve coumpond action potential threshold. [provided by MGI curators]
