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 sequence change replaces isoleucine, which is neutral and non-polar, with phenylalanine, which is neutral and non-polar, at codon 1053 of the OTOGL protein (p.Ile1053Phe). This variant is present in population databases (rs188793584, gnomAD 0.2%). 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: 227819). 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: "Possibly Damaging"; Align-GVGD: "Class C0"). 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. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The I1053F variant in the OTOGL gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The I1053F variant was not observed in approximately 5900 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The I1053F variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position where amino acids with similar properties to Isoleucine are tolerated across species. In silico analysis predicts this variant is probably damaging to the protein structure/function. We interpret I1053F as a variant of uncertain significance. -

p.Ile1053Phe in exon 27 of OTOGL: This variant is not expected to have clinical significance because it has been identified in 0.51% (16/3110) of East Asian chr omosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.o rg; dbSNP rs188793584). -
