MGI Phenotype

FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] The tectorial membrane is an extracellular matrix of the inner ear that contacts the stereocilia bundles of specialized sensory hair cells. Sound induces movement of these hair cells relative to the tectorial membrane, deflects the stereocilia, and leads to fluctuations in hair-cell membrane potential, transducing sound into electrical signals. Alpha-tectorin is one of the major noncollagenous components of the tectorial membrane. Mutations in the TECTA gene have been shown to be responsible for autosomal dominant nonsyndromic hearing impairment and a recessive form of sensorineural pre-lingual non-syndromic deafness. [provided by RefSeq, Jul 2008]
PHENOTYPE: Homozygous null mice exhibit a tectorial membrane that is detached from the cochlear epithelium. Though the basilar membranes of mutant mice are tuned, sensitivity is attenuated. Mice with an Y1870C mutation have a disrupted tectorial membrane, elevated neural thresholds and broadened neural tuning. [provided by MGI curators]
