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.Ala2516Thr in exon 44 of OTOG: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals, sug gesting that variants at this position are tolerated. Of note, 5 mammals (Bactri an camel, elephant shrew, oposum, Tasmanian devil, and wallaby) have a threonine (Thr) this position despite high nearby amino acid conservation. In addition, c omputational prediction tools do not suggest a high likelihood of impact to the protein. The variant has been reported in 2/802 African chromosomes by the Exome Aggregate Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs548278514) . -
