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

The p.Gly1356Glu variant in TECTA has not been previously reported in individual s with hearing loss or in large population studies. Computational prediction too ls and conservation analyses do not provide strong support for or against an imp act to the protein. In summary, the clinical significance of the Gly1356Glu vari ant is uncertain.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.4067G>A (p.G1356E) alteration is located in exon 11 (coding exon 11) of the TECTA gene. This alteration results from a G to A substitution at nucleotide position 4067, causing the glycine (G) at amino acid position 1356 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
