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.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.69).

BP6

Variant 11-121189171-T-C is Benign according to our data. Variant chr11-121189171-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 45342.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00756 (1151/152294) while in subpopulation AFR AF = 0.0251 (1045/41560). AF 95% confidence interval is 0.0239. There are 20 homozygotes in GnomAd4. There are 544 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 20 AR,AD gene
