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.,USH1C,AIE-75,DFNB18,DFNB18A,NY-CO-37,NY-CO-38,PDZ-45,PDZ-73,PDZ-73/NY-CO-38,PDZ73,PDZD7C,ush1cpst,harmonin,Cell Biology & Developmental Biology,Apoptosis,Neuroscience,USH1C
