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.

This sequence change replaces proline, which is neutral and non-polar, with threonine, which is neutral and polar, at codon 3 of the OTOGL protein (p.Pro3Thr). This variant is present in population databases (rs539100194, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with OTOGL-related conditions. ClinVar contains an entry for this variant (Variation ID: 291136). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Collection Method: clinical testing

The p.Pro3Thr variant in OTOGL has not been previously reported in any individua l with hearing loss, but has been reported in an individual with unknown clinica l status in ClinVar (Variation ID 291136). It has also been identified in 12/486 50 European chromosomes by the Genome Aggregation Database (gnomAD, http://gnoma d.broadinstitute.org; dbSNP rs539100194). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogen ic role. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinica l significance of the p.Pro3Thr variant is uncertain. ACMG/AMP Criteria applied: None. -
