Genes affected

OTOG (HGNC:8516): (otogelin) The protein encoded by this gene is a component of the acellular membranes of the inner ear. Disruption of the orthologous mouse gene shows that it plays a role in auditory and vestibular functions. It is involved in fibrillar network organization, the anchoring of otoconial membranes and cupulae to the neuroepithelia, and likely in sound stimulation resistance. Mutations in this gene cause autosomal recessive nonsyndromic deafness, type 18B. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2014]

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Jun 16, 2015

The p.Glu2692Lys variant in OTOG has not been previously reported in individuals with hearing loss, but has been identified in 0.1% (10/7590) of South Asian chr omosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.o rg). Although this variant has been seen in the general population, its frequenc y is not high enough to rule out a pathogenic role. Computational prediction too ls and conservation analysis do not provide strong support for or against an imp act to the protein. In summary, the clinical significance of the p.Glu2692Lys va riant is uncertain. -
