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 -10 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.008750081).
• BP6: Variant 11-17559606-G-A is Benign according to our data. Variant chr11-17559606-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 227763.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

p.Arg441Gln in exon 11 of OTOG: This variant is not expected to have clinical si gnificance because the arginine (Arg) at position 441 is not conserved through s pecies, with five mammals (Egyptian jerboa, brush-tailed rat, cat, tenrec, platy pus) having a glutamine (Gln) at this position. This variant has been identified in 0.43% (7/1632) of Finnish chromosomes by the Exome Aggregation Consortium (E xAC, http://exac.broadinstitute.org; dbSNP rs528799547). -
