p.Asp351Gly (GAT>GGT): c.1052 A>G in exon 9 of the PDHX gene (NM_003477.2) A variant of unknown significance has been identified in the PDHX gene. The D351G variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The D315G 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. 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. Therefore, based on the currently available information, it is unclear whether this variant is a pathogenic mutation or a rare benign variant. The variant is found in MITONUC-MITOP panel(s).
