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]

Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineJul 05, 2017The p.Arg626Trp variant in OTOG has been identified by our laboratory in 2 indiv iduals with hearing loss; however, a variant affecting the other copy of the OTO G gene was not identified in either of them. This variant has been identified in 0.2% (19/8420) of Ashkenazi Jewish chromosomes by the genome Aggregation Databa se (gnomAD, http://gnomad.broadinstitute.org; dbSNP rs201183725). Although it ha s been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Computational prediction tools and conservation analysis do not provide strong support for or against an impact to the protein. In summar y, the clinical significance of the p.Arg626Trp variant is uncertain. -
