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]

Val873Met in exon 26 of USH1C: This variant is has been identified in 1/3738 (0. 02%) of African American chromosomes in a broad population by the NHLBI Exome se quencing project (http://evs.gs.washington.edu/EVS/). It is not expected to have clinical significance due to a lack of conservation across species, including m ammals. In addition, computational analyses (PolyPhen2, SIFT, AlignGVGD) do not suggest a high likelihood of impact to the protein. -
