Genes affected
OTOF (HGNC:8515): (otoferlin) Mutations in this gene are a cause of neurosensory nonsyndromic recessive deafness, DFNB9. The short form of the encoded protein has 3 C2 domains, a single carboxy-terminal transmembrane domain found also in the C. elegans spermatogenesis factor FER-1 and human dysferlin, while the long form has 6 C2 domains. The homology suggests that this protein may be involved in vesicle membrane fusion. Several transcript variants encoding multiple isoforms have been found for this gene.

The p.Arg1376Ser variant in OTOF has not been previously reported in individuals with hearing loss, but has been identified in 1/66700 of European chromosomes b y the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org). Comp utational prediction tools and conservation analyses suggest that the Arg1376Ser variant may not impact the protein, though this information is not predictive e nough to rule out pathogenicity. In summary, the clinical significance of the p .Arg1376Ser variant is uncertain. -
