GeneDx RCV000487684 SCV000568533 uncertain significance not provided 2018-05-21 criteria provided, single submitter clinical testing The H755Y variant in the CDH23 gene has been reported previously in a few individuals with Usher syndrome; however, additional clinical and familial segregation information were not included in these reports (Oshima et al., 2008; Bonnet et al., 2011). In addition, the H755Y variant was observed in an consanguineous family with Usher syndrome type 2, where a USH2A nonsense variant was found to co-segregate with disease in homozygous individuals (Le Quesne Stabej et al., 2012). The H755Y variant is observed in 250/30,740 (0.81%) alleles from individuals of South Asian background, including one homozygous individual, in large population cohorts (Lek et al., 2016). The H755Y variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In-silico analyses, including protein predictors and evolutionary conservation, support that this variant does not alter protein structure/function. We interpret H755Y as a variant of uncertain significance.
