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]

OTOG (HGNC:):

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.001714617).
• BP6: Variant 11-17634898-G-A is Benign according to our data. Variant chr11-17634898-G-A is described in ClinVar as [Benign]. Clinvar id is 226910.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-17634898-G-A is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.104 is higher than 0.05.

not specified Benign:2

Benign, criteria provided, single submitter	clinical testing	GeneDx	Oct 23, 2017	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. -
Benign, criteria provided, single submitter	clinical testing	Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine	Nov 24, 2014	Arg2524His in exon 44 of OTOG: This variant is not expected to have clinical sig nificance because it has been identified in 13.6% (24/176) of Yoruba (Nigerian) chromosomes from a broad population by the 1000 Genomes Project (http://www.ncbi .nlm.nih.gov/projects/SNP; dbSNP rs114242958). -
