Description

The L2460R variant in the CDH23 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The L2460R variant is not observed in large population cohorts (Lek et al., 2016). The L2460R 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. This substitution occurs at a position that is conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret L2460R as a variant of uncertain significance.
