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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineApr 12, 2016The p.Ala2129Val variant in OTOG has not been previously reported in individuals with hearing loss, but has been identified in 1/206 of Chinese chromosomes by t he 1000 Genomes Project (dbSNP rs535700451). Although this variant has been seen in the general population, its frequency is not high enough to rule out a patho genic role. Computational prediction tools and conservation analysis suggest tha t the p.Ala2129Val variant may impact the protein, though this information is no t predictive enough to determine pathogenicity. In summary, the clinical signifi cance of the p.Ala2129Val variant is uncertain. -
