The variant was not observed in approximately 6,500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a common benign variant in these populations. The A298P variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties; however, this substitution occurs at a position that is not conserved. A missense variant in a nearby residue (L303S) has been reported in the Human Gene Mutation Database in association with fumarase deficiency (Stenson et al., 2014), supporting the functional importance of this region of the protein. Based on the currently available information, we consider this variant to be likely pathogenic; however, the possibility that it is benign cannot be excluded.
