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.Ser164Leu variant in OTOGL has not been previously reported in individuals with hearing loss, but it has been identified in 4/30742 South Asian chromosome s by the Genome Aggregation Database (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs377611164). Although this variant has been seen in the general populatio n, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analyses do not provide strong support for or against an impact to the protein. In summary, the clinical significance of the p.Ser164Leu variant is uncertain. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.491C>T (p.S164L) alteration is located in exon 7 (coding exon 7) of the OTOGL gene. This alteration results from a C to T substitution at nucleotide position 491, causing the serine (S) at amino acid position 164 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces serine with leucine at codon 164 of the OTOGL protein (p.Ser164Leu). The serine residue is moderately conserved and there is a large physicochemical difference between serine and leucine. This variant is present in population databases (rs377611164, ExAC 0.02%). This variant has not been reported in the literature in individuals with OTOGL-related conditions. ClinVar contains an entry for this variant (Variation ID: 504843). 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. -
