p.Lys387Gln (AAG>CAG): c.1159 A>C in exon 11 of the PDHA1 gene (NM_000284.3). A variant of unknown significance has been identified in the PDHA1 gene. The K387Q variant has not been published as a mutation, nor has it been reported as a benign polymorphism to our knowledge. The K387Q variant was not observed with any significant frequency in approximately 6500 individuals of European and African American ancestry in the NHLBI Exome Sequencing Project. The K387Q variant is a semi-conservative amino acid substitution, which may impact secondary protein structure as these residues differ in some properties. This substitution occurs at a position that is conserved across species. In silico analysis predicts this variant likely does not alter 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).
