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.Arg864Cys variant in OTOF has not been previously reported in individuals with hearing loss, but has been identified in 6/9980 African chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs1500 70091). Computational prediction tools and conservation analysis suggest that th is variant may impact the protein, though this information is not predictive eno ugh to determine pathogenicity. In summary, the clinical significance of the p.A rg864Cys variant is uncertain. -
