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]

The c.6329-3C>G variant in OTOG has not been previously reported in individuals with hearing loss or in large population studies, but has been identified in 1/5 2118 European chromosomes by the genome Aggregation Database (gnomAD, http:// ht tp://gnomad.broadinstitute.org/; dbSNP rs201371081). This variant is located in the 3' splice region. Computational tools suggest a possible impact to splicing. However, this information is not predictive enough to determine pathogenicity. In summary, the clinical significance of the c.6329-3C>G variant is uncertain. -
