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]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The p.Ser763Phe variant in USH1C has not been previously reported in individuals with hearing loss or Usher syndrome, but has been identified in 1/59738 Europea n chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstit ute.org; dbSNP rs140313023). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Comp utational prediction tools and conservation analysis do not provide strong suppo rt for or against an impact to the protein. In summary, the clinical significanc e of the p.Ser763Phe variant is uncertain.

Collection Method:clinical testing

The c.1388C>T (p.S463F) alteration is located in exon 18 (coding exon 18) of the USH1C gene. This alteration results from a C to T substitution at nucleotide position 1388, causing the serine (S) at amino acid position 463 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
