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.

Submissions by phenotype

not specified Benign:2
Benign, criteria provided, single submitterclinical testingGeneDxAug 22, 2017This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
Benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMar 01, 2011Ile1806Ile in exon 43 of OTOF: This variant is not expected to have clinical sig nificance because it has been identified in a similar frequency in Chinese cases (5/146 (3.4%) chromosomes) and controls (8/192 (4.2%) chromosomes) (Wang 2010). In addition, this variant has been identified by our laboratory in three indivi duals; two of whom have another genetic etiology for their hearing loss. Further more, this variant does not alter an amino acid residue and is not located near a splice junction. -
Autosomal recessive nonsyndromic hearing loss 9 Benign:1
Benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaApr 27, 2017This 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 rule this variant out of causing disease. Therefore, this variant is classified as benign. -
