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]

Arg636Cys in Exon 18 of USH1C: This variant has been reported in one individual with prelingual severe to profound deafness with no vision abnormalities (Ouyang 2002). However, this variant is not expected to have clinical significance beca use it has been identified in 0.5% (20/3738) of African American chromosomes fro m a broad population by the NHLBI Exome Sequencing Project (http://evs.gs.washin gton.edu/EVS; dbSNP rs149510892). In addition, this variant has been identified by our laboratory in a proband who carried two pathogenic variants in another ge ne. -
