Genes affected

OTOGL (HGNC:26901): (otogelin like) The protein encoded by this gene belongs to the otogelin family. This gene is expressed in the inner ear of vertebrates with the highest level of expression seen at the embryonic stage and lowest in adult. Knockdown studies in zebrafish suggest that this gene is essential for normal inner ear function. Mutations in this gene are associated with autosomal recessive deafness.

The p.Ala713Asp variant in OTOGL has not been previously reported in individuals with hearing loss. This variant has been identified in 1/66580 European chromos omes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs769499824). Although this variant has been seen in the general populatio n, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Ala713Asp variant is uncertain. -
