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.Ala1555Thr in exon 35 of OTOG: This variant is not expected to have clinical s ignificance due to a lack of conservation in mammals. Of note, three mammals (sq uirrel, manatee, Cape golden mole) have a threonine (Thr) at this position. It h as been identified in 0.6% (5/774) of African chromosomes by the Exome Aggregati on Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs545740473). -
