The T191I variant in the SDCCAG8 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The T191I variant is observed in 21/10,386 (0.2%) alleles from individuals of African background in the ExAC dataset (Lek et al., 2016). The T191I 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 that is not conserved, and in silico analysis predicts this variant likely does not alter the protein structure/function. We interpret T191I as a variant of uncertain significance.
