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]

Significance: Benign
Review Status: criteria provided, single submitter
Collection Method: clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Ala871Thr in Exon 26 of USH1C: This variant is not expected to have clinical sig nificance because it has been identified in 0.5% (35/7020) of European American chromosomes from a broad population by the NHLBI Exome Sequencing Project (http: //evs.gs.washington.edu/EVS; dbSNP rs56165709). In addition, this variant has be en reported in one individual with Usher type 1 who carried two other truncating USH1C variants assumed to explain disease, one in cis with Ala871Thr (Zwaenepoe le 2001). -

NM_005709.3(USH1C):c.1646+1145G>A is an intronic variant classified as a variant of uncertain significance in the context of USH1C-related disorders. c.1646+1145G>A has been observed in cases with relevant disease (PMID: 24416283, 25333064). Functional assessments of this variant are not available in the literature. c.1646+1145G>A has been observed in population frequency databases (gnomAD: NFE 0.53%). In summary, there is insufficient evidence to classify NM_005709.3(USH1C):c.1646+1145G>A as pathogenic or benign. Please note: this variant was assessed in the context of healthy population screening. -
