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]

Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Jan 24, 2023	In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -
Uncertain significance, criteria provided, single submitter	clinical testing	Invitae	Aug 22, 2022	This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 507 of the USH1C protein (p.Gly507Ser). This variant is present in population databases (rs142652588, gnomAD 0.05%). This variant has not been reported in the literature in individuals affected with USH1C-related conditions. ClinVar contains an entry for this variant (Variation ID: 178562). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Dec 15, 2013

The Gly807Ser variant in USH1C has not been previously reported in individuals w ith hearing loss, but has been identified in 0.03% (3/8586) of European American chromosomes by the NHLBI Exome Sequencing Project (http://evs.gs.washington.edu /EVS/; dbSNP rs142652588). Computational analyses (biochemical amino acid proper ties, conservation, AlignGVGD, PolyPhen2, and SIFT) do not provide strong suppor t for or against an impact to the protein. In summary, additional data is neede d to determine the clinical significance of this variant. -
