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

This variant is present in population databases (rs200392453, ExAC 0.03%). This sequence change replaces glutamine with arginine at codon 1180 of the OTOGL protein (p.Gln1180Arg). The glutamine residue is highly conserved and there is a small physicochemical difference between glutamine and arginine. This variant has not been reported in the literature in individuals with OTOGL-related conditions. ClinVar contains an entry for this variant (Variation ID: 504850). 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. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Gln1180Arg variant in OTOGL has been previously reported by our laboratory in 1 individual with hearing loss; however, a variant affecting the remaining copy of OTOGL was not identified. It has been identified in 0.04% (56/125812) of European chromosomes by gnomAD (http://gnomad.broadinstitute.org/). Computational prediction tools and conservation analyses suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the p.Gln1180Arg variant is uncertain. ACMG/AMP Criteria applied: PP3, PM2_Supporting. -

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.3539A>G (p.Q1180R) alteration is located in exon 30 (coding exon 30) of the OTOGL gene. This alteration results from a A to G substitution at nucleotide position 3539, causing the glutamine (Q) at amino acid position 1180 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
