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 histidine, which is basic and polar, with leucine, which is neutral and non-polar, at codon 1295 of the OTOGL protein (p.His1295Leu). This variant is present in population databases (rs187723280, gnomAD 0.1%). 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: 229119). 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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Variant classified as Uncertain Significance - Favor Benign. The p.His1295Leu va riant in OTOGL has not been previously reported in individuals with hearing loss , but has been identified in 0.2% (15/9632) of African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs187723280) . Computational prediction tools and conservation analysis suggest that this var iant may not impact the protein, though this information is not predictive enoug h to rule out pathogenicity. In summary, while the clinical significance of the p.His1295Leu variant is uncertain, its frequency suggests that it is more likely to be benign.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.3884A>T (p.H1295L) alteration is located in exon 33 (coding exon 33) of the OTOGL gene. This alteration results from a A to T substitution at nucleotide position 3884, causing the histidine (H) at amino acid position 1295 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
