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]

Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpApr 24, 2023For these reasons, this variant has been classified as Pathogenic. ClinVar contains an entry for this variant (Variation ID: 1069904). This variant has not been reported in the literature in individuals affected with USH1C-related conditions. The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This sequence change creates a premature translational stop signal (p.Arg80Glyfs*6) in the USH1C gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in USH1C are known to be pathogenic (PMID: 10973247, 17407589, 20301442, 21203349). -
