The A48V variant in the WFS1 gene has not been reported previously as a pathogenic variant, nor asa benign variant, to our knowledge. This variant is not observed in large population cohorts (Lek etal., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The A48V variant is aconservative amino acid substitution, which is not likely to impact secondary protein structure asthese residues share similar properties. This substitution occurs at a position that is not conserved. Insilico analysis predicts this variant likely does not alter the protein structure/function. We interpretA48V as a variant of uncertain significance.
