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.Ala1136Val variant in OTOGL has been identified by our laboratory in 1 ind ividual with hearing loss, but the variant did not segregate with disease in an affected sibling. It has also been identified in 3/64954 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP r s374368341). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational predic tion tools and conservation analyses do not provide strong support for or agains t an impact to the protein. In summary, the clinical significance of the p.Ala11 36Val variant is uncertain. -

The c.3407C>T (p.A1136V) alteration is located in exon 29 (coding exon 29) of the OTOGL gene. This alteration results from a C to T substitution at nucleotide position 3407, causing the alanine (A) at amino acid position 1136 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
