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

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 9: BayesDel_addAF, BayesDel_noAF, Cadd, Eigen, MutationAssessor, phyloP100way_vertebrate, PROVEAN, REVEL, REVEL [when dbscSNV1_ADA, dbscSNV1_RF, max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.2363073).

BP6

Variant 2-26480205-A-G is Benign according to our data. Variant chr2-26480205-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 48180.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.000722 (110/152326) while in subpopulation AFR AF = 0.00248 (103/41582). AF 95% confidence interval is 0.00209. There are 0 homozygotes in GnomAd4. There are 49 alleles in the male GnomAd4 subpopulation. Median coverage is 34. This position passed quality control check.
