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]

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

p.Pro136Leu in exon 4 of OTOG: This variant is not expected to have clinical sig nificance due to a lack of conservation across species, including mammals. Of no te, three mammals (oranutang, cow, tenrec) have a leucine (Leu) at this position despite high nearby amino acid conservation. In addition, computational predict ion tools do not suggest a high likelihood of impact to the protein. It has also been identified in 0.1% (12/11744) of East Asian chromosomes and 38/173206 tota l chromosomes by the Genome Aggregation Database (gnomAD, http://gnomad.broadins titute.org; dbSNP rs542646349). -
