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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Met1403Val variant in OTOGL has been previously identified by our laborato ry in the heterozygous state in two siblings with hearing loss due to an alterna te genetic cause in another gene and a variant affecting the remaining copy of O TOGL has not bee identified. This variant has been identified in 0.24% (26/10930 ) of Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.b roadinstitute.org; dbSNP rs774172292). Although this variant has been seen in th e general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analysis suggests that the variant may impact the protein, though this information is not predictive enoug h to determine pathogenicity. In summary, the clinical significance of the p.Met 1403Val variant is uncertain. -
