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 p.Thr2467Asn variant in OTOG has not been previously reported in individuals with hearing loss or in large population studies. Computational prediction tool s and conservation analyses suggest that this variant may not impact the protein , though this information is not predictive enough to rule out pathogenicity. I n summary, the clinical significance of the p.Thr2467Asn variant is uncertain. -
