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]

p.Arg636His in exon 18 of USH1C: This variant is not expected to have clinical s ignificance due to a lack of conservation across species, including mammals. Of note, the pika, Weddell seal, opossum, Tasmanian devil, and wallaby have a hist idine (His) at this position. In addition, computational prediction tools do not suggest a high likelihood of impact to the protein. -
