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.

p.Val375Ile, c.1123G>A (TECTA; NM_005422.2; Chr11g.120989347G>A; GRCh37): The p. Val375Ile variant in TECTA has not been previously reported in individuals with hearing loss, but has been identified in 8/126686 of European chromosomes and 2/ 30782 of South Asian chromosomes by the Genome Aggregation Database (gnomAD, htt p://gnomad.broadinstitute.org; dbSNP 752254649). Although this variant has been seen in the general population, its frequency is not high enough to rule out a p athogenic role. Computational prediction tools and conservation analysis suggest that the p.Val375Ile variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical sign ificance of the p.Val375Ile variant is uncertain. ACMG/AMP Criteria applied: PM2 ; PP3 -
