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.

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 12-80211123-T-C is Benign according to our data. Variant chr12-80211123-T-C is described in ClinVar as [Likely_benign]. Clinvar id is 1197396.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00594 (904/152218) while in subpopulation AFR AF= 0.0209 (868/41558). AF 95% confidence interval is 0.0197. There are 10 homozygotes in gnomad4. There are 436 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 10 AR gene
