Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The NM_194248.3(OTOF):c.98G>A(p.Arg33Gln) variant causes a missense change. The variant allele was found at a frequency of 0.00135 in 1,554,618 control chromosomes in the GnomAD database, including 17 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R33W) has been classified as Likely benign. The gene OTOF is included in the ClinGen Criteria Specification Registry.

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 -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.009204447).

BP6

Variant 2-26537756-C-T is Benign according to our data. Variant chr2-26537756-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 48278.

BS1

Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00675 (1027/152204) while in subpopulation AFR AF = 0.0233 (966/41524). AF 95% confidence interval is 0.022. There are 10 homozygotes in GnomAd4. There are 506 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 10 AR,Unknown gene
