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.

ACMG classification

Specifications for OTOF are available in the ClinGen Criteria Specification Registry and recommended for reference when assigning criteria.

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.61).

BP6

Variant 2-26558521-G-A is Benign according to our data. Variant chr2-26558521-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 48257.

BP7

Synonymous conserved (PhyloP=-0.401 with no splicing effect.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00246 (375/152220) while in subpopulation AFR AF = 0.00833 (346/41546). AF 95% confidence interval is 0.0076. There are 5 homozygotes in GnomAd4. There are 174 alleles in the male GnomAd4 subpopulation. Median coverage is 31. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 5 AR,Unknown gene
