Genes affected

OTOG (HGNC:8516): (otogelin) The protein encoded by this gene is a component of the acellular membranes of the inner ear. Disruption of the orthologous mouse gene shows that it plays a role in auditory and vestibular functions. It is involved in fibrillar network organization, the anchoring of otoconial membranes and cupulae to the neuroepithelia, and likely in sound stimulation resistance. Mutations in this gene cause autosomal recessive nonsyndromic deafness, type 18B. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, May 2014]

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BP6: Variant 11-17634292-A-T is Benign according to our data. Variant chr11-17634292-A-T is described in ClinVar as [Benign]. Clinvar id is 226909.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-17634292-A-T is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.175 is higher than 0.05.

7516+11A>T in intron 43 of OTOG: This variant is not expected to have clinical s ignificance because it is not located within the conserved splice consensus sequ ence. It has been identified in 25.3% (43/170) of European American chromosomes from a broad population by the 1000 Genomes Project (http://www.ncbi.nlm.nih.gov /projects/SNP; dbSNP rs12277962). -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
