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 Pro1106Thr variant in OTOF has not been previously reported in individuals w ith hearing loss or in large population studies. Computational prediction tools and conservation analyses suggest that the Pro1106Thr variant may impact the pro tein, though this information is not predictive enough to determine pathogenicit y. In summary, the clinical significance of the Pro1106Thr variant is uncertain. -
