Genes affected
USH1C (HGNC:12597): (USH1 protein network component harmonin) This gene encodes a scaffold protein that functions in the assembly of Usher protein complexes. The protein contains PDZ domains, a coiled-coil region with a bipartite nuclear localization signal and a PEST degradation sequence. Defects in this gene are the cause of Usher syndrome type 1C and non-syndromic sensorineural deafness autosomal recessive type 18. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2009]

Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.Asn51Ser variant in USH1C has not been previously reported in individuals with hearing loss or Usher Syndrome, but has been identified in 1/16428 South As ian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinst itute.org; dbSNP rs775363189). Although this variant has been seen in the genera l population, its frequency is not high enough to rule out a pathogenic role. Co mputational prediction tools and conservation analyses suggest that the p.Asn51S er variant may not impact the protein, though this information is not predictive enough to rule out pathogenicity. In summary, the clinical significance of the p.Asn51Ser variant is uncertain. -
