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.

Variant classified as Uncertain Significance - Favor Benign. The Val1298Ala vari ant in OTOF has not been reported in the literature nor previously identified by our laboratory. Computational analyses (biochemical amino acid properties, homo logy, PolyPhen2, SIFT, AlignGVGD, splicing assessment) do not provide strong sup port for or against pathogenicity. -
