Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BS1BS2

The NM_194248.3(OTOF):c.1630C>T(p.Arg544Cys) variant causes a missense change. The variant allele was found at a frequency of 0.000749 in 1,609,512 control chromosomes in the GnomAD database, including 2 homozygotes. 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. R544H) has been classified as Uncertain significance. 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 -8 ACMG points.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000901 (134/148792) while in subpopulation NFE AF = 0.00174 (116/66596). AF 95% confidence interval is 0.00148. There are 0 homozygotes in GnomAd4. There are 67 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 2 AR,Unknown gene
