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: Uncertain significance
Review Status: criteria provided, single submitter
Collection Method: clinical testing

The F463L variant in the OTOG gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The F463L variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The F463L variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved in mammals, however, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret F463L as a variant of uncertain significance. -
