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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Met282Thr variant in SERPINB6 has not been previously reported in individu als with hearing loss, but has been identified in 1/11578 Latino chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs 374321672). Although this variant has been seen in the general population, its f requency is not high enough to rule out a pathogenic role. Methionine (Met) at p osition 282 is not conserved in mammals or evolutionarily distant species, raisi ng the possibility that a change at this position may be tolerated. Additional c omputational prediction tools do not provide strong support for or against an im pact to the protein. In summary, the clinical significance of the p.Met282Thr va riant is uncertain.
