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.Ala359Thr variant in OTOGL has not been previously reported in individuals with hearing loss, but has been identified in 5/93662 European chromosomes by t he Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs767747155). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational predi ction tools and conservation analyses do not provide strong support for or again st an impact to the protein. In summary, the clinical significance of the p.Ala 359Thr variant is uncertain. -
