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 p.Ser851Ala var iant in USH1C has not been previously reported in individuals with hearing loss or Usher syndrome; however, this variant has been identified in 0.2% (16/8650) o f East Asian chromosomes by the Exome Aggregation Consortium (ExAC, http://exac. broadinstitute.org; dbSNP rs200779709). Although this variant has been seen in t he general population, its frequency is not high enough to rule out a pathogenic role. The serine (Ser) at position 851 is not conserved in mammals or evolution ary distant species, and one mammal (ferret) has an alanine (Ala) at this positi on supporting that a change at this position may be tolerated. In summary, while the clinical significance of the p.Ser851Ala variant is uncertain, these data s uggest that it is more likely to be benign. -
