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]

This sequence change creates a premature translational stop signal (p.Arg155*) 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). This variant is present in population databases (rs377145777, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with Usher syndrome (PMID: 17407589, 25356976, 27460420). ClinVar contains an entry for this variant (Variation ID: 371731). For these reasons, this variant has been classified as Pathogenic. -
