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.

Significance: Likely benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant was observed as part of a predisposition screen in an ostensibly healthy population. A literature search was performed for the gene, cDNA change, and amino acid change (where applicable). Publications were found based on this search. The evidence from the literature, in combination with allele frequency data from public databases where available, was sufficient to determine this variant is unlikely to cause disease. Therefore, this variant is classified as likely benign. -

The heterozygous p.Arg822Trp variant in OTOF has been identified in 2 siblings from 1 family with non-syndromic deafness (PMID: 16283880). However, these affected individuals were also homozygous for a nonsense variant in OTOF and this variant was also present in unaffected individuals (PMID: 16283880). This variant has also been identified in >2% of European (Finnish) chromosomes and 18 homozygotes by ExAC (http://gnomad.broadinstitute.org/). In summary, this variant meets criteria to be classified as benign for autosomal recessive non-syndromic deafness. -
