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.Thr512Ala variant in OTOGL has not been previously reported in individuals with hearing loss, but has been identified in 1/15438 Latino chromosomes and 1/ 61276 European chromosomes by the Genome Aggregation Database (gnomAD, http://gn omad.broadinstitute.org; dbSNP rs187504761). Although this variant has been seen in the general population, its frequency is not high enough to rule out a patho genic role. Computational prediction tools and conservation analysis suggest tha t the variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the p.Thr512Ala variant is uncertain. -
