Genes affected

OTOGL (HGNC:26901): (otogelin like) The protein encoded by this gene belongs to the otogelin family. This gene is expressed in the inner ear of vertebrates with the highest level of expression seen at the embryonic stage and lowest in adult. Knockdown studies in zebrafish suggest that this gene is essential for normal inner ear function. Mutations in this gene are associated with autosomal recessive deafness.

OTOGL (HGNC:):

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.75).
• BP6: Variant 12-80254580-T-A is Benign according to our data. Variant chr12-80254580-T-A is described in ClinVar as [Benign]. Clinvar id is 227811.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr12-80254580-T-A is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.000874 (1264/1446948) while in subpopulation AMR AF= 0.0038 (169/44474). AF 95% confidence interval is 0.00333. There are 0 homozygotes in gnomad4_exome. There are 613 alleles in male gnomad4_exome subpopulation. Median coverage is 29. This position pass quality control queck.
