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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). ClinVar contains an entry for this variant (Variation ID: 229301). This variant has not been reported in the literature in individuals affected with TECTA-related conditions. This variant is present in population databases (rs201860044, gnomAD 0.07%). This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 1366 of the TECTA protein (p.Thr1366Met). -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Thr1366Met variant in TECTA has not been previously reported in individual s with hearing loss, but has been identified in 0.1% (10/11376) of Latino chromo somes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs201860044). Computational prediction tools and conservation analysis su ggest that the p.Thr1366Met variant may impact the protein, though this informat ion is not predictive enough to determine pathogenicity. In summary, the clinica l significance of the p.Thr1366Met variant is uncertain. -
