The S2117A variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to our knowledge. This variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). The S2117A variant is a non-conservative amino acid substitution, which is likely toimpact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. This substitution occurs at a position where amino acids with similar properties to Serine are tolerated across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. Therefore, based on the currently availableinformation, it is unclear whether this variant is a pathogenic variant or a rare benign variant.
