A variant of uncertain significance has been identified in the ATP6V0A2 gene. The C196W variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. The C196W variant is not observed in large population cohorts (Lek et al., 2016). The C196W 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; and in silico analysis predicts this variant is probably damaging to the protein structure/function. Based on the currently available information, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
