Genes affected
USH1G (HGNC:16356): (USH1 protein network component sans) This gene encodes a protein that contains three ankyrin domains, a class I PDZ-binding motif and a sterile alpha motif. The encoded protein interacts with harmonin, which is associated with Usher syndrome type 1C. This protein plays a role in the development and maintenance of the auditory and visual systems and functions in the cohesion of hair bundles formed by inner ear sensory cells. Mutations in this gene are associated with Usher syndrome type 1G (USH1G). Alternative splicing results in multiple transcript variants. [provided by RefSeq, Sep 2013]

Uncertain significance, criteria provided, single submitter | clinical testing | Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine | Jul 06, 2015 | The p.Arg269Gln variant in USH1G has not been previously reported in individuals with hearing loss or Usher syndrome, but has been identified in 1/64314 Europea n chromosomes by the Exome Aggregation Consortium (ExAC, http://exac.broadinstit ute.org; dbSNP rs753080270). Although this variant has been seen in the general population, its frequency is not high enough to rule out a pathogenic role. Comp utational prediction tools and conservation analysis do not provide strong suppo rt for or against an impact to the protein. In summary, the clinical significanc e of the p.Arg269Gln variant is uncertain. - |
