Genes affected

OTOA (HGNC:16378): (otoancorin) The protein encoded by this gene is specifically expressed in the inner ear, and is located at the interface between the apical surface of the inner ear sensory epithelia and their overlying acellular gels. It is prposed that this protein is involved in the attachment of the inner ear acellular gels to the apical surface of the underlying nonsensory cells. Mutations in this gene are associated with autosomal recessive deafness type 22 (DFNB22). Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

Collection Method:clinical testing

c.180-12C>T in intron 4 of OTOA: This variant is not expected to have clinical s ignificance because a C>T change at this position does not diverge from the spli ce consensus sequence and is therefore unlikely to impact splicing. It has been identified in 4/66460 of European chromsomes and 3/11448 Latino chromosomes by t he Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs7 76210902). -
