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 testingGeneDxFeb 17, 2023Canonical splice site variant predicted to result in a null allele in a gene for which loss of function is a known mechanism of disease; Not observed at significant frequency in large population cohorts (gnomAD); This variant is associated with the following publications: (PMID: 32581362, 28041643, 17407589) -
Pathogenic, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpFeb 07, 2023This variant results in the deletion of part of exon 9 (c.748_759+5del) of the USH1C gene. It is expected to disrupt RNA splicing. Variants that disrupt the donor or acceptor splice site typically lead to a loss of protein function (PMID: 16199547), and loss-of-function variants in USH1C are known to be pathogenic (PMID: 10973247, 17407589, 20301442, 21203349). This variant is present in population databases (no rsID available, gnomAD 0.007%). This variant has been observed in individuals with Usher syndrome (PMID: 17407589, 28041643). ClinVar contains an entry for this variant (Variation ID: 437936). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -
