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

The Pro1111Leu variant in OTOF has not been previously reported in individuals w ith hearing loss, but has been identified in 0.14% (6/4406) of African American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu/ EVS/; dbSNP rs141972928). Computational prediction tools and conservation analys is suggest that this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, additional informa tion is needed to fully assess the clinical significance of this variant. -
