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]

OTOP2 (HGNC:19657): (otopetrin 2) Predicted to enable proton channel activity. Predicted to be involved in proton transmembrane transport. Predicted to be located in plasma membrane. Predicted to be integral component of membrane. [provided by Alliance of Genome Resources, Apr 2022]

The -1C>T variant in USH1G has not been reported in individuals with hearing los s. The frequency of this variant in large European American and African American populations cannot be determined from the NHLBI Exome Sequencing Project (http: //evs.gs.washington.edu/EVS/) because coverage at this position was insufficient . This variant is located in the 5'UTR at the -1 nucleotide position and is cons erved across species; though this information is insufficient to assume pathogen icity. Although we cannot rule out a deleterious impact on the regulation of spl icing or translation of USH1G, to date no disease-causing variants have been fou nd in this region of the transcript. In summary, additional information is neede d to determine the clinical significance of this variant. -
