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]

Variant classified as Uncertain Significance - Favor Benign. The Lys732Glu varia nt in USH1C has not been reported in the literature nor previously identified by our laboratory. However, this variant was observed in a broad population (dbSN P rs148168494) suggesting it could occur with reasonable frequency in the genera l population. Computational analyses (biochemical amino acid properties, homolog y, PolyPhen2, SIFT, AlignGVGD) do not provide strong support for or against path ogenicity. In summary, the clinical significance of this variant cannot be deter mined at this time; however, based on identification of this variant in this ind ividual who has another cause for their clinical features and in dbSNP we would lean towards a more likely benign role. -

This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 432 of the USH1C protein (p.Lys432Glu). This variant is present in population databases (rs148168494, 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: 47994). 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: "Benign"; 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. -
