Genes affected
OTOGL (HGNC:26901): (otogelin like) The protein encoded by this gene belongs to the otogelin family. This gene is expressed in the inner ear of vertebrates with the highest level of expression seen at the embryonic stage and lowest in adult. Knockdown studies in zebrafish suggest that this gene is essential for normal inner ear function. Mutations in this gene are associated with autosomal recessive deafness.

Gln1014Gln in exon 27 of OTOGL: This variant is not expected to have clinical si gnificance because it does not alter an amino acid residue and is not located wi thin the splice consensus sequence. It has been identified in 4.6% (9/194) of Lu hya (Kenyan) chromosomes from a broad population by the 1000 Genomes Project (ht tp://www.ncbi.nlm.nih.gov/projects/SNP; dbSNP rs144125797). -
