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.

This sequence change creates a premature translational stop signal (p.Arg1495*) in the OTOF gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in OTOF are known to be pathogenic (PMID: 18381613, 19250381, 22575033). This variant is present in population databases (rs147321712, gnomAD 0.003%). This premature translational stop signal has been observed in individual(s) with autosomal recessive nonsyndromic deafness (PMID: 18381613, 29293505). ClinVar contains an entry for this variant (Variation ID: 65804). For these reasons, this variant has been classified as Pathogenic. -
