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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineNov 10, 2016The 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. -
Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The 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. -
