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:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg183*) in the OTOGL gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in OTOGL are known to be pathogenic (PMID: 23122586). This variant is present in population databases (rs397514588, gnomAD 0.007%). This premature translational stop signal has been observed in individual(s) with moderate hearing loss (PMID: 23122586). ClinVar contains an entry for this variant (Variation ID: 39779). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -

Significance:Pathogenic

Review Status:no assertion criteria provided

Collection Method:clinical testing

The OTOGL c.547C>T variant is predicted to result in premature protein termination (p.Arg183*). This variant was reported along with a splicing variant in three siblings with sensorineural hearing loss (Yariz. 2012. PubMed ID: 23122586; Oonk. 2014. PubMed ID: 24378291). This variant is reported in 0.0074% of alleles in individuals of European (Non-Finnish) descent in gnomAD (http://gnomad.broadinstitute.org/variant/12-80623121-C-T). Nonsense variants in OTOGL are expected to be pathogenic. This variant is interpreted as pathogenic. -
