Variant summary

Our verdict is Benign. The variant received -12 ACMG points: 1P and 13B. PP3BP4_StrongBP6BS1BS2

The NM_194248.3(OTOF):c.1424A>G(p.Glu475Gly) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.000322 in 1,613,334 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Synonymous variant affecting the same amino acid position (i.e. E475E) has been classified as Likely benign.

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: Benign. The variant received -12 ACMG points.

PP3

Multiple lines of computational evidence support a deleterious effect 7: AlphaMissense, BayesDel_noAF, Cadd, Dann, phyloP100way_vertebrate, REVEL, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationAssessor, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.021783859).

BP6

Variant 2-26482561-T-C is Benign according to our data. Variant chr2-26482561-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 48168.

BS1

Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.000204 (31/152326) while in subpopulation AMR AF = 0.00176 (27/15308). AF 95% confidence interval is 0.00124. There are 0 homozygotes in GnomAd4. There are 15 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 5 AR gene
