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]

Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineSep 11, 2016p.Asn2186Ser in exon 38 of OTOG: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, more than 5 mammals have a serine (Ser) at this position despite high near by amino acid conservation. In addition, the variant has been identified in 7/13 22 of African chromosomes by the 1000Genome Project (http://www.1000genomes.org/ ; dbSNP rs368261417). -
