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 asparagine, which is neutral and polar, with tyrosine, which is neutral and polar, at codon 1402 of the OTOGL protein (p.Asn1402Tyr). This variant is present in population databases (rs770438244, 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: 505424). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests 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. -

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Asn1402Tyr variant in OTOGL has not been previously reported in individual s with hearing loss. This variant was identified in 2/8374 East Asian chromosom es by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; db SNP rs770438244); however, its frequency is not high enough to rule out a pathog enic role. Computational prediction tools and conservation analyses do not provi de strong support for or against an impact to the protein. In summary, the clini cal significance of the p.Asn1402Tyr variant is uncertain. -

Collection Method: clinical testing

The c.4204A>T (p.N1402Y) alteration is located in exon 35 (coding exon 35) of the OTOGL gene. This alteration results from a A to T substitution at nucleotide position 4204, causing the asparagine (N) at amino acid position 1402 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
