The V2331I variant in the FAT4 gene has not been reported previously as a pathogenic variant, nor as a benign variant, to our knowledge. The V2331I variant is not observed in large population cohorts (Lek et al., 2016). The V2331I 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 not conserved. In silico analysis is inconsistent in its predictions as to whether or not the variant is damaging to the protein structure/function. We interpret V2331I as a variant of uncertain significance.
