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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMar 08, 2011The Val781Ile variant in USH1C has not been reported in the literature nor previ ously identified by our laboratory. Computational analyses (biochemical amino ac id properties, homology, PolyPhen2, SIFT, AlignGVGD) do not provide strong suppo rt for or against pathogenicity. In summary, the clinical significance of this v ariant cannot be determined with certainty at this time. -

Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 21, 2022This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 481 of the USH1C protein (p.Val481Ile). This variant is present in population databases (rs397517875, gnomAD 0.03%). 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: 47998). Algorithms developed to predict the effect of missense changes on protein structure and function (SIFT, PolyPhen-2, Align-GVGD) all suggest that this variant is likely to be tolerated. 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. -
