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

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.011637777).

BP6

Variant 11-17572108-C-T is Benign according to our data. Variant chr11-17572108-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 517441.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000443 (619/1398266) while in subpopulation SAS AF = 0.00242 (192/79236). AF 95% confidence interval is 0.00214. There are 4 homozygotes in GnomAdExome4. There are 367 alleles in the male GnomAdExome4 subpopulation. Median coverage is 30. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 4 AR gene
