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]

This sequence change creates a premature translational stop signal (p.Arg44*) in the OTOG gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in OTOG are known to be pathogenic (PMID: 23122587). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with OTOG-related conditions. For these reasons, this variant has been classified as Pathogenic. -
