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]

The p.Lys210Thr variant in USH1C has not been previously reported in individuals with hearing loss or Usher syndrome. This variant has been identified in 2/6620 6 European chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.br oadinstitute.org; dbSNP rs372789934). Computational prediction tools and conserv ation analyses suggest that this variant may impact the protein, though this inf ormation is not predictive enough to determine pathogenicity. In summary, the cl inical significance of the p.Lys210Thr variant is uncertain. -

This sequence change replaces lysine, which is basic and polar, with threonine, which is neutral and polar, at codon 210 of the USH1C protein (p.Lys210Thr). This variant is present in population databases (rs372789934, gnomAD 0.004%). 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: 166393). 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: "Possibly 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. -
