not specified Uncertain:1
The V254I variant in the ALDOA gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The V254I variant is observed in 11/16490 (0.07%) alleles from individuals of South Asian background and in 13/66398 (0.02%) alleles from individuals of non-Finnish European background, in the ExAC dataset (Lek et al., 2016). The V254I variant is a conservative amino acid substitution, which is not likely to impact secondary protein structure as these residues share similar properties. This substitution occurs at a position that is conserved across species. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret V254I as a variant of uncertain significance. -
