A variant of uncertain significance has been identified in the DSG2 gene. The M1015T variant has not been published as pathogenic or been reported as benign to our knowledge. This variant is not observed at a significant frequency in large population cohorts (Lek et al., 2016). The M1015T 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. However, this substitution occurs at a position where amino acids with similar properties to methionine (M) are tolerated across species. Finally, in silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function.
