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.

Likely benign, criteria provided, single submitter | clinical testing | ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories | Dec 29, 2017 | The OTOF p.Asp1528Asn variant (rs138151478) has been reported in a patient with hearing loss who was also homozygous for a pathogenic mutation in OTOF (Romanos 2009). The p.Asp1528Asn variant is listed in the Genome Aggregation Database (gnomAD) browser with an allele frequency of 0.48% in the African population (identified in 116 out of 24,026 chromosomes), and is classified as likely benign in ClinVar (Variant ID: 48238). Therefore, based on the available evidence, the p.Asp1528Asn variant is classified as likely benign. - |

Likely benign, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jul 20, 2015 | p.Asp1528Asn in Exon 37 of OTOF: This variant is not expected to have clinical s ignificance because it has been identified in 0.4% (43/10406) of African chromos omes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs138151478). - |
Nonsyndromic genetic hearing loss Benign:1
Likely benign, reviewed by expert panel | curation | ClinGen Hearing Loss Variant Curation Expert Panel | Jul 27, 2021 | The filtering allele frequency (the lower threshold of the 95% CI of 119/24962) of the c.4582G>A (p.Asp1528Asn) variant in the OTOF gene is 0.407% for African/African-American chromosomes by gnomAD, which is a high enough frequency to be classified as likely benign based on the thresholds defined by the ClinGen Hearing Loss Expert Panel for autosomal recessive hearing loss variants (BS1). - |
