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]

p.Glu2362Lys in exon 41 of OTOG: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including several mamm als. Of note, 5 species have a lysine (Lys) at this position despite moderate ne arby amino acid conservation. In addition, computational prediction tools do not suggest a high likelihood of impact to the protein. The variant has been identi fied in 1/562 East Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs375080152). -
