Genes affected

SERPINB6 (HGNC:8950): (serpin family B member 6) The protein encoded by this gene is a member of the serpin (serine proteinase inhibitor) superfamily, and ovalbumin(ov)-serpin subfamily. It was originally discovered as a placental thrombin inhibitor. The mouse homolog was found to be expressed in the hair cells of the inner ear. Mutations in this gene are associated with nonsyndromic progressive hearing loss, suggesting that this serpin plays an important role in the inner ear in the protection against leakage of lysosomal content during stress, and that loss of this protection results in cell death and sensorineural hearing loss. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2010]

p.Met34Val in exon 3 of SERPINB6: This variant is not expected to have clinical significance because it has been identified in 0.25% (26/10406) of African chrom osomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org ; dbSNP rs145538358). In addition, methionine (Met) at this position is poorly c onserved across many mammals and all evolutionarily distant species, and computa tional tools do not predict an impact to the protein. -
