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]

Ala7Ala in exon 1 of OTOG: This variant is not expected to have clinical signifi cance because it does not alter an amino acid residue and is not located within the splice consensus sequence. It has been identified in 2.6% (5/194) of Luhya ( Kenyan) chromosomes from a broad population by the 1000 Genomes Project (http:// www.ncbi.nlm.nih.gov/projects/SNP; dbSNP rs149500671). -
