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 provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpOct 24, 2022This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 196 of the USH1C protein (p.Arg196Gln). This variant is present in population databases (rs397517883, gnomAD 0.2%). 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: 48020). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The glutamine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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. -
not specified Benign:1
Likely benign, criteria provided, single submitterclinical testingLaboratory for Molecular Medicine, Mass General Brigham Personalized MedicineMay 11, 2014Arg196Gln in exon 8 of USH1C: This variant is not expected to have clinical sign ificance because the arginine (Arg) at position 196 is not conserved in mammals or across evolutionarily distant species, and seven mammals have a glutamine (Gl n) at this position. -
