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 Thr1954Met variant in TECTA has not been previously reported in individuals with hearing loss or in large population studies. Computational analyses (bioche mical amino acid properties, conservation, AlignGVGD, PolyPhen2, and SIFT) sugge st that the Thr1954Met variant may impact the protein, though this information i s not predictive enough to determine pathogenicity. In summary, additional info rmation is needed to determine the clinical significance of this variant. -

This variant has not been reported in the literature in individuals affected with TECTA-related conditions. This variant is present in population databases (rs542600464, gnomAD 0.02%). This sequence change replaces threonine, which is neutral and polar, with methionine, which is neutral and non-polar, at codon 1954 of the TECTA protein (p.Thr1954Met). ClinVar contains an entry for this variant (Variation ID: 165371). 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. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on TECTA protein function. -
