Genes affected

TECTA (HGNC:11720): (tectorin alpha) 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.

The Arg1504Cys variant in TECTA has not been previously reported in individuals with hearing loss or in large population studies. Computational prediction tools and conservation analyses suggest that the Arg1504Cys variant may impact the pr otein, though this information is not predictive enough to determine pathogenici ty. In summary, the clinical significance of the Arg1504Cys variant is uncertain . -
