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]

Variant classified as Uncertain Significance - Favor Benign. The 1284+4C>T varia nt in USH1C has not been reported in individuals with hearing loss or in large p opulation studies. This variant is located in the 5' splice region. Computationa l tools do not suggest an impact to splicing. However, this information is not p redictive enough to rule out pathogenicity. Although position +4 is part of the splice site region, the reference sequence was already divergent from consensus (normally an A at this position) and therefore this variant is less likely to di srupt splicing. In summary, the clinical significance of this variant cannot be determined with certainty; however based upon the arguments described above, we would lean towards a more likely benign role. -
